Mash Pit: OpenID

Mash Pit is an informal all-day hackfest for collaborating on solving human problems with open APIs, open source and web-based technology. OpenID is an emerging standard for doing identity on the Internet; single sign-on, one username, one password for the sites you visit. Putting the two together we have an event that people can come to and hack on OpenID and figure out how to make it work for their sites or applications.
