You're literally talking about modifying code on every computer, router, =
printer,
and other device with an IP address as well as updating every =
application,
routing protocol, etc. Pretty much the same set of requirements for =
deploying
IPv6, but, with IPv6, we've at least already done the code on most =
computers
and routers.
To me, it sounds like the same effort as deploying IPv6, but, without =
gaining
as many bits and without having the advantage of the progress we have
already made in IPv6.
