Where can you play wrestling games online

The only method that I'm aware of is this: Buy a PS2 or Xbox (if the games support the online function) For PS2, buy either Smackdown! vs RAW or Smackdown! vs RAW 2006, connect the PS2 online and voila! Play to your heart's content! I haven't owned an Xbox so I can't say how to play the wrestling games online or even the names of the games for Xbox.
