Could you make the mapping between Python objects and C++ objects keyed off
python object ptr + python class ptr? It doesn't seem to me to be a problem
having two C++ instances lying about (except possibly for problems with object
lifetime; but that's not much hairier than it is normally). The only issue as I
see it is how you find out which C++ object supports the method call/attribute
access made from python.

Toby.
