I understand. I took issue only with the idea that any value of N could
be "right". Don't forget though that IPv4 phones also need resources
from the network - their public IPv4 addresses. Why isn't that a
showstopper too? Hm...
The essential difference with IPv6 compared to IPv4 is that (due to
address abundance) all addresses are (or at least can be) globally
routable. There can be a direct bidirectional relationship between a
connected device and the world; of necessity, that relationship brings
with it a higher degree of interdependence.
It's a pretty simple thing really: You can have all that that IPv6
offers (both now and potentially), or you can cripple it so that the
user experience is "just like IPv4".
I get where you are coming from. It's just a bit sad, is all.
