if you mean to have the game be responsive in a hurry, you'll need socket
support.  if you're talking about a slower moving kind of thing, regular
responses will be fine.

either way you're going to need a script or two on your site that can
1) let two different players find an opponent who is not already in a game
2) that keeps tracking of routing information between two opponents engaged in
a game.
