Alrighty, I just finished setting up a TetriNET server here for us, so if anyone's interested, go download a TetriNET client from here. Then enter dkpsystem.com as the "Hostname or IP Address" and click "Connect" and you're in.
For more info on Tetrinet, check out TetriNET.org. It's pretty much awesome.
