Penetration depth depends a lot on the speed with which two objects
collide, and also on the time-step duration.  It will be zero when one
object rests on another, so it's not useful for force computation.

I *think* that the joint feedback API would give you the information
you're looking for, but I haven't actually tried using it yet.
