I am almost sure the filal release will enable fast computers with T3 connections or so to serve the world, and I think the problem is not houses, but just the bulk of moving people on the client. Crystalspace would have a lot of sprites to calculate wheather to render or not, I am not sure about how crystalspace works though. The server is downloadable in source from CVS if you can figure out how to compile it, and I can\'t even figure out the client (:
