I'm already working on a similar authentication system for a rails app and this just really motivated me to release it as a plugin...
That said, I'm sure lots of other Rails developers have already built their own solution. I'm also sure some are more mature than mine (i.e. in production). Isn't uservoice.com backed by Rails? Their social authentication is so pretty Google uses it as a demo.
