If we are going to do a round by round system like Lazy has suggested and we all agree would be pretty slick, I honestly think that a webcam mounted to the top of the roof and pointing straight down would be the best bet.
I couldn't find a wifi enabled camera by Logitech or Microsoft, but with a pretty simple USB extension cable and my/curtis laptop we can do all sorts of things. No fus needed, and webcams are cheap, i was just over at Future Shop picking up Lost Planet and I scoped out the cameras and you can get a pretty good Microsoft on for $50.
