Working together Microsoft, LinkSafe and ooTao have developed the first Info-Card enabled i-broker. You can register for an i-name at LinkSafe and subsequently log in to any OpenID 2.0 relying party without ever entering a password. All of the security can be Info-Card driven.
We have made the Ruby RP Module deployed at LinkSafe available under BSD license along with a simple 'hello world' app that demonstrates driving the module.
