Yes. One facet of what I'm getting at is that users should be able to
use face-to-face interaction as an authentication mechanism if their
AFS admins wish to allow that in their cell. Right now there is a
technological barrier to this policy option.

Exactly! Especially in the case where traditional implies "on-line

I agree. I think the really tough hurdle I'm trying to get over here
in this thread is if OpenAFS is willing to accept use-cases where the
task above is delegated outside the sphere of the "AFS software suite"
(OpenAFS, Kerberos, and various extensions to Kerberos).
In particular, this use-case works much better if support for it is
ubiquitous ("on by default") in the client (but of course "off by
default" on the servers). This way users from "integrated" cells can
participate in "non-integrated" cells while still keeping the admins
of their home cell happy.
