Hmm... I'm not keen on seeing network numbers in the URCs !

FWIW, xarchie has a neat technique that lets you sort the results of
archie searches according to weights placed on domain names, e.g. for me
things in "uk" are generally preferable to things in "au" or "jp".
Something like this would probably be a useful feature in any client
which is going to deal with URCs

URCs could record things like servers' time zones (i.e. displacement
from UTC) and lat/longs. This would undoubtedly(?) be a great help for
everyone trying to figure out which server to talk to next

Now, here's a question - what price IAFA templates in all of these
discussions? I'm not clear how URCs (at least
the "URT") relate to them. What does the panel think?

Cheerio,

Martin
