Well, I posted that link because of the introduction:

"allows users to log in to many websites using one account. It was originally positioned as a single sign-on service for all web commerce."

Sounds a lot like OpenID, being Microsoft, I do not believe they actually see any benefit in supporting OpenID when they already have their own version of it.

The last thing I heard about that was that Cardspace would accept OpenID Identifiers, but nothing more than that, you know more?
