Funny you posted this. I was about to post something myself for Facebook 
apps using FBML (this is a non-issue if you use IFRAME option for FB apps).

So if we turn off form token validation using the following form_alter 
and hacking #action in system.module (probably a non-hack way to do 
this), I can get forms to submit and save data while in FBML mode. But, 
at least on user/x/edit I get a FB canvas page trying to load a FB login 
page as FBML, probably from something getting weird on redirect.

Dave, let's connect on Skype sometime this week (SN: schoolengine) as 
I'm gearing up to do my next app and want to get it all FBML instead of 
using IFRAMEs and would like to merge our FB module code and get this 
stuff solid.
