XBConnect allows you to use your computer as a "tunnel" so you can play XBox and PSP games on the internet. For XBox, it uses the "System Link Games" screen to fool it into thinking that it is on a LAN. If the game supports the use of headsets, they can also be used with XBConnect.

If you take a look at XBC's forums, you'll notice that I have replied to a few questions there.

At Matt Whitlock's request, an article about XBC is forthcoming. The article may include a picture of his bloody remains.
