Social without any authentication or authorization (one time auth)

Hi,

I have a requirement whereby I need to implement connection with Fb/Tw etc using a one time authorization. I need to setup some widgets within a website which would always display feeds for a particular user - user1. One who visits the site does not need to sign in with his/her own id and seek for authorization since user1's id has already authorized that website app to be used for user1's contents.

I see I can remove providerSignInController to get this feature but how do I authorize at least once? How do I define the userIdSource to be statically set?

Assistance will be appreciated.

thanks!
