Open-source cross-platform CardSpace extension for Firefox, as well as a Java library to act as a “relying party” (a site that uses CardSpace for authentication)

CardSpace plugin for Firefox for Windows. Uses the underlying Windows CardSpace system interface, so it works with all the other (ahem) applications using CardSpace on your PC.

I’m trying to make sense of CardSpace so I can understand what today’s OpenID announcement means. Here is the only site I’ve found on the whole bloody internet which uses a CardSpace login — and it’s merely a demo site.

MS are announcing CardSpace authentication for OpenID. Of course, five bucks says this goes the “embrace & extend” way of Microsoft “supporting” SPF two years ago.
