I think Cardspace addresses the multiple-personality issue quite well, from the user-experience perspective. I’ve been playing around with the identity selector in Firefox on my Mac, which actually works some of the time. Easily selecting a persona based on the context of a given situation (game, blog post, adult content access, etc) is as easy as clicking on an icon.

Interesting to see the verification companies starting to get involved. You need access to a lot of datasources to get out of pocket verification working.

I keep thinking of OpenID like my TypeKey ID. Nothing more, nothing less than single sign-on. OpenID now has something like over 100M potential users. Problem is, there are only a handful of sites that accept OpenID. The lag is killing the potential.
How can we avoid the flamewar that is going to erupt over who owns distributed transparent databases that store our identities?
