I've been looking for something like this for a while now but honestly if you run a non-technical service requiring your users to sign up for a github account (just to vote on features) is a pretty big ask. Integration with other AUTH services like Facebook/Google would be very beneficial.

That's a decision we made on purpose.

We figured out our early adopters would be on GitHub, that's why we started with GitHub login. Fell free to add a feature request on http://feathub.com/feathub/feathub :-)

Also, while we're at it, we could even consider anonymous voting (http://feathub.com/feathub/feathub/+15)

This raises the question of the gameability of the voting, but this could be mitigated using a mixture of cookies, captchas and browser fingerprinting.

I was always using UserVoice. It's quite cheap, and even has (or at least had) discounts for open-source/non-profit projects.
