It's still alpha quality, but it enables you to login to any OpenID consumer website using your XMPP client. (eg: [3], [4], [5])
Any chance you'll be making that code public ? One thing I would like to change is to base64-encode the JID, because I don't like my e-mail addresses hanging around cleartext in my webpages. You could easily provide both, and detect which one is used. cheers, Remko
