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. > 5) DOMAINS != ROUTES ... 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.] -- Shyy-Anzr: J.
