Wow, biggest code review ever for me. As a disclaimer, this is my first app-engine app, and I'm learning as I go along with the rest of you, so I'm sure there are plenty of shortcomings in this approach that I'll have to address as I get further along in my development. Also, since that link points directly to my subversion repository, it's probably going to be changing over time. That said, I thought the example at the bottom of the package-summary page that was linked in the OP was quite a good start.
