Doesn't seem to exist. Wish it did, but certianly not enough to wrangle that php-ball myself.
I think this is certianly a place I'd be willing to put my BTC where my mouth is, especially if it were bidirectional.
(I still have 2 friends on facebook, and it sends me planative messages about maybe I should log back in from time to time. I know I can gate twitter to facebook, but I don't think that helps me see their posts.)
