Thanks, zmove. I don't have a much better answer than the one I'm sure you expect... hopefully it'll be done by then, but there's no way to know.

My goal would be to have something to demo at Drupalcon Szeged, assuming we can make it. We're well underway, we just haven't had a chance to get things in a good state for testing and collaboration. Hopefully that'll happen sooner rather than later.
