I have been looking at something very similar. My version adds functions to
allows enscribed volumes to be set for each primative group.  The occulion
list would start empty each frame. primative groups would then be tested
against the list as they pass though the pipeline, and be added to the list.
This means you would really have to be using front to back rendering for at
least 'major' objects but can be implemented totally in the geometry
subsystem.
