How is this any different than hosting your own federated OpenID service? Hell, I'm basically doing this already with XMPP, Email and a blog, but not OpenID because it's not as prevalent as it could be. This is already a solved problem that doesn't take terabytes of storage space. Though, like any common service or protocol, it could be more secure.
