This is along the lines of a swept-volume engine, which is something 
different than what ODE is.

The problem with stopping at first contact is that you get into trouble 
when two moving objects intersect -- you have to find the common 
earliest impact. When you scale this up to N objects in a pile, all the 
objects would find impacts at the beginning of their timestep, and never 
make any progress.
