If you're looking for an institution around which to organize people and projects, I recently created Kilometa Labs for that kinda thing. Will start promoting it in a week or so after we think more about strategy &c. We have a few cool projects in the pipeline as well, so you'd be associating with cool people and cool stuff.

I think you should talk to muflax and Zak Vance about the Anki-like ideas. Will email you with more info, I've already mentioned your ideas to them.
