Well, that didn't take long...Xbox Gateway is an application that allows Xbox games that support system link (such as Halo) to play against other systems through the Internet using a virtual private network (thanks Dragon[THC]). The program is currently only available for Linux, but they are working on porting it to Windows and OS X. Anyone care to download this and let us know how well it works?
Only on linux? This was Peng's making. I smell it
