I agree with @dennis_h,

Gigya has some great (stable) plugins it would be nice to see this adjusted for BP. It sort of works. It will get them logged in, but its setup for WP so everything goes to the WP profile pages and not BP. I would say moding this would be ,much easier than try to make a stable version from scratch.

If this plugin would let you map FB profile info into xprofile fields, it would be exceedingly useful.
