Or storing credentials rather than username/password pairs, possibly.

But in any case, I think that's close to what we want. As I say, I  
think we need to establish a session credential of some kind that can  
be used over unencrypted sessions with some improvement in security  
over typical fixed cookies that exist today. I'm fine if one of these  
credential options happens to tie into a TLS property, but I think  
we'll have to have reasonable security over non-TLS, too. (And by  
"reasonable", I'm expecting this to be "not as good as if you had  

And I absolutely agree that this effort needs strong support from the  
browser implementors from the start - we also need the same from a  
few major webapps.
