Server non-graphical mode?

[cotharyus]

I was thinking we could skip the non-gui server part for now, and concentrate on opening up the option of more than one client computer connecting for a race. From there it's a much smaller step to an actual server.

Can anyone provide some insight into how much additional load it places on the server system to have a client logged in? Might be important information to have before going and coding a network socket that will allow 1000+ connections
