As you might already know, OpenID.sun.com has been live for a few days now. I have my shiny new OpenID (http://openid.sun.com/metadaddy) and have already used it to log in to the Project Concordia wiki and add myself to the list of participants. Everything seems to be working as it should.
It's a fitting time, then, to start explaining how we deployed OpenID, and Hubert has started doing exactly that with this blog entry on the architecture of OpenID.sun.com. As you can see from Hubert's description, the OpenID deployment is based on OpenSSO and its OpenID extension, so any interested party can go grab the source and try it out for themselves. In fact, some already have.
