Windows Cardspace: Has any website in the history of the internet ever used Windows Cardspace?

Are there any web-sites that use Windows Cardspace for authentication?

i'm tired of usernames and passwords and e-mail addresses. i never want to have to "create an account" ever again. i'm tired of memorizing usernames and passwords. i'm tired of handing over my e-mail address to every web-shite that asks for it.

i want single sign-on. If a web-site needs to know who i am: i want a UI to appear on my computer that lets me pick an identity that i will present to the web-site.

OpenID was close to this utopia, except that there's only about 15 web-sites that support it (not counting *exchange.com).

Is there any web-site, anywhere, that uses Windows Cardspace for authentication?

Your previous question - Has any website in the history of the internet ever used Windows Cardspace? - was migrated to the Web Applications site. Please go over there, create and associate an account and update that question rather then reposting here. – ChrisF Nov 25 '10 at 15:00
This is a repeat, albeit more verbose, of a previous question which was migrated to Webb Apps. – Shevek Nov 25 '10 at 15:27

VeriSign PIP and MyOpenID.

CardSpace has the disadvantage of requiring browser support (a plugin) and being impossible to use on someone else's PC [easily].

I think that's rather underestimated. For example, Disqus and IntenseDebate can be counted as two sites, but they are used by many blogs.

Both those sites ask for a username and password. They don't let me login with OpenID or Cardspace. – Ian Boyd Nov 25 '10 at 18:39
@Ian: They are OpenID providers, and they only use CardSpace as an alternate authentication method (you'll have to sign up with a password before adding an infocard). Also, the login pages on both sites do not display the InfoCard option if your browser does not support it. (For Firefox/Windows, install this. Shows the advantage of OpenID versus CardSpace, doesn't it?) – grawity Nov 26 '10 at 13:43
