yes,
it takes around 3 hours. here the guide :
1. download from jarain4j from Google code via svn !
2. make a hook to gather new created sessions (important!!) since liferay creates sessions a bit odd. use a simple map with key = sessionId and value = session
3. now create a servlet as done janrain4j's basic servlet (token servlet)
4. in that servlet you do pretty much as done in the liferay's facebook code. ie. update/create user
5. create another hook for autologin and read from the session you manipulated in your token servlet mentioned in 3. that needs additional shared session attributes in the portal properties btw.
If you still have trouble to read your session variables, disable phishing in portal.properties (sorry)
that's it !
