I tried to do this once before by adding an index value to the CurveMap(?) struct so they could be dereferenced into the enclosing CurveMapping but it was rejected by Campbell. This way doesn't really fit into the rest of the rna functions (not to mention py-dogma) since you're operating on a 'child' through the 'parent' interface. But, alas, this one little thing is the *only* reason you can't create materials using the py-api so it really needs a good solution.
