I'd probably start out by computing a bunch of points on the surface and 
using the Inside test to figure out an approximate center of 
gravity...but I know virtually nothing about this kind of thing, so this 
is just guesswork.

Maybe limit it to mesh objects, that way you could also simulate the way 
the surface is deformed by it's interactions with other objects. I don't 
think the deform patch would be sufficient for this...and handling only 
meshes should make it easier.
