* '''Market testing''': Virtual exovivaria could cover a wide range of designs. They might have different gravities, ecosystems, sizes, layouts and maintenance problems. The ones  that attract the most game-players per launched (virtual) pound might be the best sources of ideas. Terrestrial exovivaria prototypes could be based on the more successful virtual ones, at least insofar as their success doesn't depend on low gravity or [[microgravity]]. And real exovivaria would offer better user experiences if game- and ecosystem-designers designed them with a full understanding of gravity (low, variable, or even negligible) as a design parameter. Until actual exovivaria are launched, populated, and in full swing, the best guesses about what they should be like for users will require interpolating between virtual exovivaria and terrestrial prototypes.

*'''Human resource 'filtering'''': Any virtual world is likely to be visited by [[http://en.wikipedia.org/wiki/Griefer | Griefers]] - those who are intent only on making trouble. Prototype exovivaria and real ones in orbit can be damaged (including the killing of living things) even without malicious intent. In particular, with launch costs being high, exovivaria might represent several thousands of dollars per pound of sunk costs just for transportation to [[LEO]]. They might contain equipment for managing [[orbital debris]] damage that saboteurs could also use to disable an entire exovivarium. It's important to catch this sort of user before they can add further risks to such a high investment. The most accessible virtual exovivaria could serve as [[http://en.wikipedia.org/wiki/Honeypot_(computing) | honeypots]] - places where abusers might be attracted, identified, isolated and blocked.

* '''Procedural rehearsals''': Exovivaria will not be all fun and games. There will be repair and rescue operations too. [[Orbital debris]] strikes might be the biggest issue. Repairs and rescues will need to be choreographed. It would be wise to rehearse such operations in simulations, before trying them out in terrestrial prototypes (where mistakes might cost hundreds or thousands of dollars) or in launched exovivaria (where a totally disabling error could cost millions). The simulations might use more advanced computational resources, going to a level of physical detail not used in game play, in order to bring the more subtle risks to the surface. In general, more detailed simulation is more expensive simulation. The high costs and risks for prototyping exovivaria (not to speak of orbiting real ones) would make ever-more-detailed simulation worth the cost.

*'''Variable realism''' - the paying users might want nearly photorealistic rendering -- they will want to know "what it's really going to be like." However, the paid worker-avatars might prefer a more schematic view. This would save on (simulated) satellite downlink costs, but it should also boost productivity. Some [[telepresence]] studies have shown that workers are less distracted and feel greater "flow" (immersion) when shown only what's required for the job being done in the remote scene.

*'''Variable interaction bandwidth''' - real exovivaria will probably be in low-earth-orbit ([[LEO]]). Such orbits are good when there are ground stations in contact with an exovivarium, because the speed-of-light delays will be imperceptibly short. However, it also means there will be times when there is no direct link with the ground - the Earth itself is in the way. For some given notional orbit, the simulated communication with the simulated environment might be degraded by a (likewise, simulated) round-trip delay through a geosynchronous satellite. The link might even be available only sporadically, as is the case with some LEO satellites, if it can't relay its messages to another satellite that's more Internet-accessible.

To be sure, the augmentations couldn't directly cause anything in the simulated ''physical'' environment. A user, through an avatar, might direct a simulated telebot to pluck a leaf, but the avatar itself couldn't do the plucking.

Apart from this limit of "ghostliness" in the augmentations, however, allowing users to draw on any [[MMORPG]] concept could be very useful in market-testing. Let's say that the augmentations grow to the point where they begin to cloud the simulated exovivarium. They might even reach the point where they reduce user interest in maintaining the ecosystem being simulated. That bad trend would be an excellent game-design diagnostic: it would say that the reality you're trying to simulate is not compelling enough, and that an exovivarium must have more of ''something'', or else it will be abandoned.[^The virtual world users' knowledge that it's a simulation, where things can't really die, might make any such diagnosis a lot less meaningful. But that's an important purpose of the more expensive terrestrial prototypes (where real living things ''can'' die): to calibrate the virtual worlds against real [[biophilia]]. Some interplay between the two design spaces should be expected.^]

If and when exovivaria become real, virtual exovivaria will probably still be useful. They might even become more popular than ever.

To own some real estate in a real exovivarium, perhaps bossing a few telebot and avatar crews to add value to one's property in orbit ... this might be the social pinnacle of [[Project Persephone]] society. But pinnacles invite climbers. Virtual exovivaria could form the foothills and lower slopes.

People need to start somewhere in any society, and in Project Persephone, many of them won't start with much money at all. Some will even start with the idea of making money in exovivaria that others have paid for - whether virtual, terrestrially prototyped, or orbiting. For the chance of getting to the point of making things happen in orbit (whether for fun or profit), many people might move first through the virtual exovivarial worlds, learning the ropes and the ethics. Then they might move onward to terrestrial analogues, learning yet more. After climbing a naturally-forming ladder of ascent, they might eventually earn the right to do real work and own real things within real exovivaria. After all, real exovivaria are likele to remain ''relatively'' scarce for quite a while. Scarcity can sometimes do more than enhance the perception of value. It can also induce a sense of value into the steps and stages required to qualify for, or afford, the thing that's scarce.

But again, because of the high costs and risks for prototyping exovivaria (not to speak of orbiting real ones), more detailed simulation should be worth the cost.

*'''Variable interaction bandwidth''' - real exovivaria will probably be in low-earth-orbit ([[LEO]]). That's good if there are ground stations in contact with it, because the speed-of-light delays will be imperceptibly short. However, it also means there will be times when there is no direct link with the ground. For some given notional orbit, the simulated communication with the simulated environment might be degraded by a (likewise, simulated) round-trip delay through a geosynchronous satellite. The link might even be available only sporadically, as is the case with some LEO satellites, if it can't relay its messages to another satellite that's more Internet-accessible.

That's good if there are ground stations in contact with it, because the speed-of-light delays will be imperceptibly short. However, it also means there will be times when there is no direct link with the ground. At those times, the simulated communication with the simulated environment might be degraded by a (likewise, simulated) round-trip delay through a geosynchronous satellite. The link might even be available only sporadically, as is the case with some LEO satellites, if it can't relay its messages to another satellite that's more Internet-accessible.

To own significant real estate in a real exovivarium, perhaps bossing a few telebot and avatar crews to add value to one's property, both in augmented reality and in physical reality terms - that might be the social pinnacle.  But people have to start somewhere in any society, and many of them won't start with much money at all. Some will even start with the idea of making money. For the chance of getting to the point of making things happen in orbit (whether for fun or profit), many people might move first through the virtual exovivarial worlds, learning the ropes and the ethics, then moving onward to terrestrial analogues and learning yet more, climbing a naturally-forming ladder of ascent. After all, real exovivaria will remain scarce for quite a while. Scarcity not only creates the perception of value, but that perception induces value into steps and stages required to qualify for, or afford, the thing that's scarce.

But people have to start somewhere, and for the chance of getting to the point of making things happen in orbit, moving first through the virtual exovivarial worlds, learning the ropes and the ethics, then moving onward to terrestrial analogues and learning yet more, will be a naturally-forming ladder of ascent for most customers. Scarcity not only creates value, it induces value into steps and stages required to qualify for, or afford, the thing that's scarce.
