I really like the idea, and what few bits of criticism I had you have already seemed to address. I just wanted to compliment you on something specifically that I though was really great: the registration process. Very similar, no confirmation fields, and, most importantly, I was signed in immediately after clicking finish. It didn't take me away from or reload the page I was on, and it didn't ask me to confirm my email. The small things really matter.
