We've got people here in Manchester who are interested in passing about
Kerberos credentials so they can access AFS from their jobs. (I don't
need it for what I do, but they do.)

As far as I know, they don't say anything much about the actual list of
available applications. Or rather they do, but they don't describe any
interoperable basis for actual naming of applications: the names are
just arbitrary strings in the GLUE model. Without some kind of catalog
of standard names, it'll be really hard to make progress on interop on
the basis of GLUE here (except within restricted domains where such
catalogs are unnecessary).

This is strongly in the scope of GLUE; if they can't do it, they need to
know soon! :-)

Sounds like you want to use/profile the Usage Record. FWIW, I've had
enhanced job execution engines in the past which exposed a UR as a
property of the job resource once the job completed (so that
distribution of the record could be done via WS-Notification, which I
had easily to hand at the time). As far as I could see, it worked quite
reasonably.

I can shove my oar in in quite a few places. :-)

Donal.
