I'm in need of an idea of how to get a single game working on two computers,
with two players.

can anyone please give me an indication of the server installation
requirements, if any.

usually i code using classic or .net ASP.

many thanks.

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.
