That's pretty cool. Can I suggest though, that sharing easily on other platforms will be important (at least as a stepping stone)? So that might involve building a facebook app that shows shared photos as well as the default one. Even though this might seem counter to #deletefacebook, I think you need to let people take small steps to taking their data back.
Totally, I'm into that. One of the big motivators here is how painful it is currently to move _your_ photos (or any personal data) across services. We want to build an open system where you control where your data goes and how. It seems like a great idea to have outbound integration like that for sure.
