I just stumbled across this today while reading xlr8yourmac, I guess it's along the same lines as frontrow although I think it is a more usable and sleek setup. It seems to lend itself well to a car computer. It aparently works with the front-row remote as well as the other ones out there like the keyspan ones. Not sure on how this thing would work with a touchscren as the mouse seems to do nothing.

It's awesome and free so give it a shot:
