I've had classification and iGeom working for about 5 years now, at least in a query-only mode; making it work to 
support modifications wouldn't be that difficult, but it will require us working together on it, as we've begun to do 
with Quikan.  The request to add support to iMesh/iMeshP for classification will be/could be a show stopper at least for 
me, since I will not bind iMesh and iGeom together in terms of code dependencies.
