Actually, you DO have an ILib2Provider object, wrapped in Python by 
PyIUnknown.  You should be able to call the methods and properties of 
ILib2Provider using that object.

Python doesn't know it's an ILib2Provider, because that's just a name 
used in the C++ source code, but the methods and properties should all 
be there.
