Microsoft Xbox System Link

Microsoft Xbox System Link allows you to play games on your LAN. We tried it today with Unreal Tournament 3, but could only get games to join when both consoles were either wired or wireless. Mixing and matching wired and wireless didn't work. You could see the hosted game, but joining results in an error.

Hopefully this saves someone else some head scratching.
