Sadly, this is not the case. I am currently working for a large media company that had/has relatively close ties with members of the FB dev team. The position I hold now was previously occupied by a fellow who went to work for FB and was a key interface with them over the last year and a half for things like FB Connect. I can tell you now that we got no privileged documentation that anyone else didn't. The only thing we really got was a poor guy who heard our complaints a little too often and wasn't really able to do much to help out.
