Global warming of the identity ocean
The big news out of the RSA conference is the announcement of a "marriage" of OpenID and CardSpace. For those that aren't up on the inner workings of user-centric identity: CardSpace is Microsoft's instantiation of the InfoCards Meta-system that Kim Cameron proposed several years ago; OpenID is a URL-centric identity protocol that has grown up with the grassroots nurturing of players like Sxip Identity, JanRain, Verisign, Cordance, Six Apart, and Netmesh.
