Right, except OpenID isnıt going to do this; there needs to be an
infrastructure in place where OpenID (or some other standard persistent
identifying system) can sit on top of, and thatıs still the big problem.
Now, maybe the tail will wag the dog, and OpenID will lead to efforts to
build underlying trust infrastructure, but at the moment, that
infrastructure does not exist. The easiest way to implement that
infrastructure probably would be for every institution that might adopt
OpenID to also become an OpenID provider, but then, unless there is a
standard mechanism for linking one OpenID to another in a secure manner,
weıre back at having multiple OpenIDs depending on our context. I completely
agree that IP-based authentication is not the long-term answer; maybe there
is a path, however, to applying OpenID over our current IP-based auth /
proxy servers in a manner that does add user-side value. As Nathan stated in
an earlier email, the one big advantage OpenID has right now is that it is
easy to start playing with, and maybe thatıs enough to start the wagging.
