Nice idea! I'd be interested in giving it a try for our project in the future.
It does seem that the demo review is broken in Safari, I get a JS error and the UI doesn't seem to work completely:
> [Error] TypeError: e.connect is not a function. (In 'e.connect(l,s)', 'e.connect' is undefined)
Also, is there any way to keep up-to-date on the project? I don't see a newsletter or Twitter link on your homepage.
