Shane and Joanie.
I have met with Dominic Mazzoni of Google and Jamie Teh of NVDA here at the CSUN conference.
I now have a much clearer understanding of the available python libraries and approaches to build the ATTA for MSAA+IAccessible2.
It looks like the best bet to start is to fork PYIA and extend it to support IAccessible2:

Examples of usage of PYIA:

I have PYIA demos running on my computer and even build a copy of NVDA, so I have more confidence in the Python approach to MSAA+IAccessible2.
It looks like python is the way to go for the ATTA for MSAA+IAccessible2.
