My prototype does that, but *without* being tied to OpenID -- a
separate cookie gets set (tied to PHP session ID, so the client
contains NO sensitive information, regardless of what's stored), and
that is used for the basis of login. You could use a MySQL DB, flatfile,
Passport, OpenID, or whatever other authentication means you like (even,
potentially, allowing login through any of OpenID -or- Passport -or- a
local DB...). Solving the SSO integration problem generically means
that everybody wins -- not just sites that chose to use OpenID.
