It is a 3 HD TV demo, and if you look closely it is powered by 3 Xboxs, with the center screen being the server and the 2 others being in some kind of client mode (look at the car selection pic, you can see "left" and "right" on other 2 screens). I asked the rep and they said that this would be a feature when it ships. I also snagged some pics of the "Xbox 360 Launcher" application that they were using to load it up (after it crashed a couple times), pretty interesting stuff.
Check out the pics:
I didn't get a chance to try it out, didn't want to stand in line for an hour, but the graphics look really good.
Also found this video on Mika Salo driving the sim:
