Hi Mike,
In case you haven't been following the SO question, I've added another answer
which is basically Erwin's solution done with SQLAlchemy. Feel free to use all
or part of the code I've put up in any additions you make to the SQLA docs. I
think people could really benefit from seeing the

Hah! When you said I'd have to wait for a patch, I didn't expect to get one
same-day!
Thanks so much for your help with this Mike. After all this, I'll definitely be
donating to SQLAlchemy when I get paid next Thursday :)

I am using a single table scheme to store for a set of resource types.
I would like to load a specific class if a mapper is defined and use the
