After much fiddling around, I was finally able to integrate Steam into my XBMC setup for my living room PC. I set up Advanced Launcher to point to my Steam games. I added some artwork to the games selection screen and now I have in my opinion a very nice ten foot interface to choose my games with. Once I exit the game it returns me full screen to XBMC. I also set it up to where I can control the whole thing with an Xbox controller.
It would be nice if the setup process was a little easier to do however. When I add new movies or shows into XBMC the scrapers grab all the correct info and artwork 99% of the time. When I was adding my games, the scrapers were very unreliable. They got the info correct, but I had to do some searching for images to get some nice looking ones.
