Really interesting.
This overlaps quite a bit with what I'm thinking about and working with... within a very different domain... (continental) philosophy.
I suggest you look into object oriented ontology, as that seems essential to some of the choices you're implicitly making on the level of programming, which may very well work but which have extensive consequences for the way Nth Society will work.
Also, I suggest you look into Baudriallard and his understanding of simulation. Without at least acknowledging that level of reality that he expresses, you might encounter some problems.
Overall, HIGHLY interesting project. Let's discuss this!
This underlies many of the questions I have after reading the post (not Baudrillard specifically, but my understanding that such issues relate to the immense differences between motivations we have in RL versus those we have for engaging online). Very applicable point!
