cks has done some work adding bounding boxes/spheres with the goal of
adding object-avatar collision detection. I'm not sure how adaptable this
work is to interobject collision detection; hopefully he'll chime in here.

In any event, wiring OpenVRML to do interobject collisions is going to
take some work. I'd definitely consider a patch to add such functionality.
I think Contact and/or Cortona have implemented  extensions for
interobject collisions; it may be a good idea to model the interface after
what they've done.
