I have a little doubt about this, because the change in the phone charges
is not a linear function of the distance.  Thus delivering a message by 3
"short" hops usually costs a lot more than delivering it by two longer ones
(or, ESPECIALLY, one to a particular state, and then one by a non-local
intrastate call).  The geographic domains also don't take into account the
fact that many large corporations have special phone arrangements to reduce
their costs for calls within the company.

       ... and only imply routings for the dumbest of sites.

Well, then, offer a counter-argument.  I've already advanced an argument
that domains do equal routes in many cases for all but an omniscient
nameserver; and that, in fact, domain-ed site names can't even be
considered to be "names" in a formal sense of the word.

[It would help to define "route", though.]
