Chat Server
I have never officially released this code as open source, however, if I get enough encouragement I may. It was basically a medium for testing out a few thoughts, but is a very functional Chat Server. The only client available is a command line app., but shows what would need to be done for any client.
In general the chat server would need some sort of client agent. The backend is an XML-RPC server.
