Getting close, which is why I previously proposed using DNS to find the
URN->URL/URC server for the publisher, a simple efficient cached,
hierarchical scheme that we dont have to re-invent.

Once the appropriate server, or servers, are found then doing the lookup is
simple and efficient.

One big advantage of this scheme - unlike several proposed recently - is
that servers aren't loaded with more queries than neccessary, allowing it
to scale both in terms of the number of URNs and the number of queries.
