I'll try to clarify with a use-case:

You have a Facebook account but I do not; you want to see my photos 
and other personal data, but I am not willing to create a Facebook 
account or otherwise subject my data to Facebook's policies. 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?
