[OpenID] OpenID 2.0 directed identity - Facebook / Microsoft

[Luke Shepard]

XAuth isn't an authentication or a distribution technology, so that part doesn't make sense.

To your specific use case: yes, it's possible for a Facebook user to share photos with people who aren't on Facebook. They can just send them an email with a link. That also applies for a few other things on the site (such as sending a message, or inviting someone to an event).

XAuth seems indicated, or you can use the OpenID associated with your Facebook page to log into *my* sites and authenticate yourself as an approved recipient of that data - except that, for this to happen, *my* sites have to be willing to accept your logins from Facebook without, necessarily, giving you an account there. So, flip it around; if you want to share *your* photos with *me*, do you have to use XAuth so Facebook can send them to my site, or can Facebook accept my OpenID so it knows that *I'm* the user who you wanted to see everything?

With differences in ToS between various sites, I see a severe distinction between "OpenID will let you share your profile data on one service with users on another service." and "OpenID will let you sign up for an account at sites you already didn't want to have an account at."
