But we have to engineer this in some fashion that
permits efficient use of these addresses by hosts and (especially) routers.
(An earlier poster wrote that you "just have to write the code". That's
wrong idea -- big iron routers don't use "code" to do forwarding, they use
silicon, and very fast silicon at that. There are routers in production
today that are handling OC-192 -- 10 Gbps -- links. You can't do that in
Software, firmware, its a matter of semantics. Do you think that silicon
magically performs routing and logical functions. Hmmm...
