Fyi btw for what its worth.
Ive been playing around working a script that will display an SMF via FB at the FB spec max width while displaying 'normal' via the forums url. No FB auth/id info is needed ie: no page asking you for 'basic info' and whatnot. The FB users could not be linked from their forum name to their FB account unless their names match... like 'Thrash' or if people dig around the FB status comments.
I KNOW you want a simple thing. The script is just a if refer = thing. I also know about separation of church and life. It's just a idea to bind the new, fb, and the old, l-g.
I think I'll rejoin FB and demo it as a-s via my home puter. I hate xmas.
