Windows Live ID CardSpace Support

Finally you can sign-in to sites that support Windows Live ID i.e. any Microsoft site, using an Information Card. Hopefully after this kind of commitment from Microsoft we will start seeing more sites add support for Information Cards. Like OpenID it would only be really successful once there are enough consumer sites (or relying parties to be specific) that supports the technology.

The next step would be if Windows Live would become an Identity Provider and allow users to download Windows Live based Information Cards so we can start maintaining our identities in only a single location. Self-Issued cards is fine but ideally I'd like to maintain my profile in only one place, that place not being my own machine.

As a side note, I plan to add Information Card support to Identitu.de (A small experiment in Facebook/OpenID integration) in early September which will allow you to download Information Cards backed by your Facebook profile.
