Appleseed uses identities that look just like an email address. For instance, mine is: michael.chisari@developer.appleseedproject.org My public profile then is: developer.appleseedproject.org/michael.chisari When I'm logged into my home node, I can go to any other Appleseed node, and "remote login" with my Appleseed identity. From there, it uses the same flow as OpenID, just in a more user-friendly fashion. It's all quite painless for the end user.
