Alan, It would be possible to expose the boolean operations filter in ParaView without much trouble. However, that filter is limited to polydata-to-polydata intersection (a plus for Jeff's application), and works best when the geometries overlap but do not share faces (a minus for Jeff's application). For Jeff's needs, I don't think it would be that useful.
