I just stumbled upon an anniuncement by Ron Fedkiw that he plans to release parts of his PhysBAM library including a real-time rigid body engine. Scroll down to the bottom of his website here:

Some of those renders there are just incredible. I am in awe. It's awesome that he's releasing even a small bit of it.
