It was discussed during the IPng days. My view at the time -- and my =
view today -- is that there's an inherent conflict between that and =
multiple competitive ISPs. Suppose there's an IP address corresponding =
to 40.75013351 west longitude, 73.99700928 north latitude (my building, =
according to Google maps). To which ISP should it be handed for =
delivery? Must all ISPs in a given area peer with each other?
