Maybe it's a good thing to think multilanguage just from the start. There are more and more "foreigners", so english native speakers may become a minority group soon ;)

I for myself do not belive that "static monster servers" are the best way to go into the future. Pure P2P has some problems (information may be lost somewhere). But what about a combination? A ring of safe servers as "last resort" for information primarily held in a P2P-Network (no, not bitorrent, something more specialized to the problem). And perhaps a bit of "Seti at home" for Poserproblems (from searchengine up to render-ring).
Based on a solid concept this may start with just one single server.
