Windows Tablet RealTimeStylus in Python

I have a Windows Tablet machine, running XP Tablet Edition, and I want to access the stylus data from Python. If anyone has done this themselves, I'd be very grateful for a description of what worked. Otherwise, I'd be grateful for advice. I'm in way over my head, so what I describe below is prob
