+an issue to be considered: for ways of authentication that don't explicitly mention the user name (and that would be everything but password; especially OpenID), there has to be a way to prevent users from hijacking an admin's account. the user wouldn't get more privileges, but the admin could find himself logged in as a user instead of an admin when he logs in using his OpenID, for example. he could fix it by removing the openid from the user's ("his") page, but it has to be taken care of nevertheless. --[[chrysn]]
