At this point, the service would connect the photo sharing of different services to the user based on their choice (I use Flickr, so I share Flickr, or I use Facebook so I'll share that with everyone). There is more functionality than in a standard Facebook App, but Facebook apps (and open social apps, and iPhone apps, etc) would be part of the solution. The service is based on sharing from the services a user already uses, but there's nothing stopping the service from helping users discover new services that are perfect for what they want to do.
