I may be giving folks too much credit but i imagine each organization will have its own independent architecture. I can just imagine landing on some world occupied by a cult like organization with their own warped idea of churches.
I think it will be kind of cool to check out the shanty towns of smaller organizations compared to 800+ member organizations. ( if you have 800 people you better have a lead architect or its going to look like 800+ 10 year old on a Minecraft server)
