Have you considered integrating something like Persona? While I have never like FB sign up, this is the exact situation where I would be tempted to use it. Possible interest, but I don't really wanna go through the sign-up. I keep hoping to find a site in the wild using Persona. of course... in the time I typed this I could have just signed up. :P
