Over the weekend, I participated in little experiment: The first ever Xbox Live death-match from a moving vehicle. Let me explain. With the help of Jake Ludington, Brandon Wirtz over at XYHD.TV wanted to take his Xbox Live playin on the road. So they loaded up Brandons 07 Jeep Wrangler with a 23 Samsung LCD and hooked it up to an Xbox 360. They took a laptop and connected it to the free Google WiFi service (only available in Mountain View, California) and using Internet Connection Sharing, connected the Xbox to play over Xbox Live. You can see the full video here. I was actually in Seattle at home as the guy at the other end playing in the video, but it was a fun experiment anyway. And let me be perfectly clear: This is not a supported method to use your Xbox 360 or connect to Xbox Live, but kudos to you if you can make it work.
Jake has more details and pictures over on his blog.
