Hi Bex, I wouldn't quite call it rogue hacking :) The OpenID provider is built as a normal Facebook application on top of the Facebook Platform. At the moment I enable basic relationship exporting in XFN format if the consumer supports OpenID2 and the Attribute Exchange Extensions. You can read more about it on my blog at http://armanddp.net or test the relationships export at http://identitu.de/test_auth/login. Let me know if you have any more questions. (Currently XFN support is more a POC but better support coming next week)
