yeap, looks nice!
I've just had a read about it (and sent a question (in french, it 
helps!) to the author).
The problem is that it seems to be slower than discreet detections 
(hehe, we can't have both good detection and speed... too bad!).
All samples also speak about only two bodies, and one stills, while the 
other moves.

In a general rigid-bodies algo, I think it's a real problem, as often 
 there are many bodies...
