Microsoft employee Andy Pennell asks in his blog whether or not the launch of Halo 2 on November 9 will affect Microsoft's overall corporate productivity. Although XBL won't work on the company's network, apparently System Link games and tunnelers do. In fact, one of the comments on Andy's blog mentions a tunneler we seem to have missed before now: Xlink Kai. In theory it will run on Windows, MacOS and LInux and can tunnel for the Xbox, GameCube or PS2. In practice, only the Windows client is available right now.
Thanks Louis Wu at HBO for the heads-up.
