I doubt they could do anything about drivers on your computer though--no modifications to the actual hardware there.
I have a 360 but not Kinect yet, waiting for the "killer" games to come out first. I definitely see it as higher potential than Move though, especially since MS said in interview with GT that you can use both the 360 controller and Kinect at the same time.
Just because M$ doesn't condone it doesn't mean they are going after people in the legal scene. Once you own a product you can do whatever you want with it. They can restrict services to you but they have no legal ground to stand on if you want to use it on your computer or in another application.

Bingo. Homebrew hackers are probably fine. I'd really like to see some official Kinect interface support in Windows 8, though. This would be especially nice for a HTPC setup!
