Intergrating punbb forum into facebook/bebo app

Hi Basically what I want to do, is to have a forum running within my bebo/facebook apps, which is based on punbb. So need a patch/front for punbb. Couple of things which need to be done: 1. The login/register system will need to be ripped out basically. And replaced with an automatic user login system, basically assigning $user to $facebook->require_add or the equivalent. 2. The CSS is going to be mostly ripped out, and many elements wrapped in fbml tags instead. 3. After a user adds the app, it should insert their name, facebookid, profilepicture url, etc into the respective fields on the user table. 4. Currently when displaying a post it's like: username avatar That's going to have to be <fb:name> <fb-profile-pic> to display the user's full name + profile pic as defined on facebook/bebo. Please quote me for the above. Let me know what php based scripts you are familar with, and whether they currently include punbb, and the facebook api. (mostly fbml)
