OpenID looks a promising way of federating your identity, reducing multiple logins, etc. Where I work at the moment they have an Active Directory which you can use on all company systems whether internal or external facing (Internet). I think these systems only work when lots of people trust them. I will track this one.

OpenID: an actually distributed identity system: "In short, OpenID is a way for individuals to create identity online and use it anywhere OpenID is supported."
