programming for a LAN

With some games(warcraft, command & conquer, etc...) you have the
possibilitie to play against each other on a LAN (Local Area Network). I
also want to program something like that with Delphi. If somebody knows
how to do something like this, please E-mail me. I'm also interested in
knowing if I can something like this with telnet or TCP/IP or some other
protocol.
