this goes for any game with no LAN capabilities and is Internet only.
I've tested this with Forza 3 on Xbox Live, so the principle should hold for any other game as well.
To LAN, just connect all the PCs to a router connected to the Internet. The only data sent over your Internet Connection is the match making and the results. The actual game is handled locally, the data takes the shortest route between all the available PCs.
So as long as everyone in the game is sitting in a room connected to the same router, all the game traffic will be handled as if it was a LAN game. With the stats being uploaded to the servers afterwards.
