A vital question here, then, is whether the user values privacy 
enough to forgo this level of convenience. Short of opting to 
automatically grant all RP requests (and never prompt user for 
re-authentication to the OP - it can still expire, just don't bother 
the *user* with renewing it), there is no way to "intelligently" 
practice selective login for the user.

>"Click to proceed", yes,

There shouldn't even be that, though. Just go to the site and see the 
page. No matter how much you abstract the process of authenticating, 
if they have to take steps to have the service recognize them then 
it's a login.
