Throughout these discussions the assumption is made that URNs will
render URLs hidden, out-of-sight, process-to-process. Is this really the
case? It seems to me that we need both a handle for specific copies of a
document, and the generic ISBN-like name.

If I write a monograph or scan a photo or publish a visualization file,
and I want to announce same on a mailing list, it would be nice to have
an agreed-upon standard syntax to use. And it'd be nice if users reading
their news could click on the reference and their favorite browser would
go get the document. Let's say I don't expect my file to live very long,
to make it into various URN registries, and my readers really shouldn't
have to do a URN lookup just to grab this thing. (Rhetorical question:
will mapping from URN to URL be as fast as domain lookups, or as slow as
Archie searches?)

So it seems there is a need for humans to be able to pass these handles
around. With or without URNs, we need URLs that humans can quote and
can paste -- whether it's via two forms of URL, or one friendly one.
