It's great to see this product finally released, congratulations! I have been waiting to get my hands on a fully open CardSpace implementation and would like to demonstrate it at work as well. I can't tell you how important this will be for a number of organisations.

Obviously, this capability is most impressive and also easiest to test when we have a *client-side* authentication module that holds the user's authentication tokens. Server-side modules are OK for application-to-application authentication, but authentication based on individual (human) identity is key, because even operations performed by an application are done on behalf of a user. Traceability needs to exist. It's a compliance requirement.

A module for Linux (esp Ubuntu, Fedora and SLED) would be very welcome.
