The way we do this in other 3D systems is to intersect a ray with the 
geometry. The ray goes between the point last frame and the point this 
frame to see if there was an intersection. In the case of the sphere, 
the two end points are the center. If there is, you can then modify the 
results accordingly. In the ODE case, I would imagine you could create 
your own contact joint at the point of intersection of the line and
