Shannon,

Fork (Kernel.fork), thread(Thread), or poll (see below).

If you have linux (or other unices, even), you might want to check out Michael 
Granger's excellent Ruby-Poll library 
(http://www.deveiate.org/code/Ruby-Poll.shtml) which includes a nice little 
chatserver example (you also might want to check out MUES, but just b/c it 
plainly rocks).

TCPServer (socket programming in general, actually) is a subject that comes up 
pretty regularly; you should be able to find some additional examples via 
Google.
