This topic has come up before... there are various hacks to work
around 'missed' collisions, the easiest being to simply use a smaller
timestep. While some cases of swept collisions are almost trivial
(e.g. sphere-sphere) in isolation, adding handling to ODE's existing
infrastructure might be quite ugly and inefficient without deep
thought -- even compared to the hacks.
