Though the service has been around a while, for
any out of the loop you can access free online console gaming via UK-based Xlink Kai. The network functions on most
current-gen machines including Xbox, PS2, PSP, Gamecube, and even the 360. A thread on the site states that the
connection is now working (albeit buggy) with Perfect Dark Zero for the
360.From the official site: "XLink Kai is a global gaming network - bringing together XBox, Playstation 2, Gamecube and PSP users, in one integrated community. It is software running on your PC or Macintosh that allows you to play system-link enabled games online for free. Kai is the only service that is not console specific, and boasts one of the friendliest communities available."

Update: Turns out you don't need to have a modded box to run the network, but modded machines will still work. Thanks to those that caught this.
