Pretty cool. Victor from Typical PC and Typical Mac user podcasts and I were playing Uno via xbox live. He picked up a 360 this past weekend. We found you can turn on a private dedicated audio chat. So there we were with our headsets on which were plugged into the wireless game controllers. At one point I was on the back porch letting the dog go out and Victor was in his kitchen. We kept talking the whole time just carrying the xbox controller like a cordless phone.
