Got OpenID more or less working on a few of these websites. Macgirvin.com and cr.unchy.com for starters. I'll extend this to other sites as I shake any remaining bugs out. 

The biggest hurdles have been in handling profile data which isn't always available via OpenID. I'm hoping there isn't a big rash of spam since this bypasses our email verification. Just have to wait and see. I don't mind self-signed identities, but they have to resolve to real identities, or they ultimately aren't worth the paper they aren't written on. 

And hardly anybody supplies their birthday in the OpenID world. I don't care so much about the birthday as the age, since this is turning into a legal requirement for social sites; and also relates specifically to the laws (i.e. the DMCA) regarding storage of personal info for youngsters.

I'll have to code around these until these issues make it into OpenID proper. They will. You can't really have a distributed identity service that doesn't map to an identity or that doesn't play along with federal law.   My own company is working on something in this space but of course I can't talk about that. 

Oh yeah - please report any bugs you encounter to the bugs forum.
