I've been haphazardly working on database definition code in the framework. It might honestly be less stupid to just develop the damned site, but the whole point is the framework, so ...
Anyway, once I have something operational, I should find out who's doing patent stuff online and thus might be interested in this. To that end, I've found one: http://fosspatents.blogspot.com/ - so once things are that far, I'll drop him a line. This post is just so I don't forget.
Here's another site: http://news.swpat.org/2010/03/transcript-tridgell-patents/ - that's actually a pretty good transcript of a talk about patent work, indicating that non-infringement is often what you really want to go for. A depatenting community should probably support workarounds as the speaker suggests at the end of the talk.
I should try to find out who's who in the field.
