I think that doing catalogs would be very difficult, since there is such a
large set of these things, and (as you say) each restricted domain has it's
own notion of the catalog. I guess in my mind it comes in two parts: first
is the mechanism to advertise locally available applications (queried with
GetFactoryAttributes) such that I know what "strings" to put in the
ApplicationName element of JSDL; second is to try to catalog a number of
"standard" application names. I think the first is straightforward and
easily doable and will provide lots of mileage in restricted domains, and
that the second is a longer term activity that will always be updated.

This seems worthwhile to pursue. Bill and I were also envisioning getting UR
updates throughout the lifetime of the job, so that you could see the
running status. This is a quite common requirement from our customers.
