Well, it would take a lot of work for people to create their own world server, and almost impossible to make it exactly like Magicosm. The client is responsible for presenting a 3D UI and sending messages to the server (that’s plenty for the client to handle the way it is). All of the game logic/rules is in the server. In fact, the server assumes that the messages could be coming from anything, the standard client, a Palm interface, a cracked version of the client, etc. So all the rules are enforced on the server. If the client is open sourced, and unique versions are created or ported (perhaps to a game console like XBox), that would only serve to increase the popularity of the Magicosm game world, which would be good business for us.
This is nothing like Blizzard’s Warcraft or Starcraft, which is really a peer to peer app with the server only helping people find each other.
