Having tried to set this up, it's a neat idea, but needs a lot more work before it's ready. Can't logout users, poor interface design, a bunch of JS errors when just trying to load a book (immediate request timeouts, incorrect paths, trying to access missing objects, non-working buttons, etc).

I hope it gets better though, because it's a great concept

EDIT: also, the forums aren't letting me register due to an error in their captcha being broken, so I can't discuss/submit my bugs there.

EDIT2: I was able submit a bug report to lanuchpad.
