OpenID and iPhone apps

I am trying to find an OpenID implementation that is similar to the way that Facebook Connect’s login mechanism works on the iPhone. I can’t find anything, which is very surprising.

Does anybody know of an open source OpenID consumer implementation for iPhone OS? And if you don’t know of one, are you looking for one?

If I can’t find one, I am going to have to write my own, and it’s something that I think would do well to be open sourced, so if you are interested, please post a comment.
