I know there are many libraries out there for OAuth and for specific sites' authentication and authorization. I'm wondering, is there any one-stop-shopping library that easily, robustly and perhaps modularly integrates with many popular social networking sites?
It would be nice to have a single library, which, given a set of IDs (FB, twitter, foursquare, etc...) would manage authorization (and maybe sessions in the case of things like FBConnect) for all.
Thanks!
