I mean last hop by that. The next hop numbers depend entirely on who else
we are connected to and our routing policy (which, incidentally, is to not
transit anything over uunet that we don't have to because they are _so_
slow these days).

check out the cflowd data exporter thing (I can't remember the specifics
of it, because we only ran it a short while do to a bug in the
experimental IOS release)... it breaks down outbound traffic by
destination AS and exports the data, so you can see who you should buy
your next connection to, etc.
