Force Feedback Mouse

from Gizmodo...

it is aware of the user's mouse gestures and can either do nothing, attract the mouse to a new position, or it push away from its current position.

I can think of some AWESOME ideas for a force feedback mouse. How (not?) cool would it be when you are playing a first person shooter to have your mouse shake when you are getting tagged. It would make it harder for the guy getting shot to respond with return fire, which I imagine it would be in real life when you are getting shot in your person.
