Unfortunately that would require *EVERY* IP stack (and probably every
library/program that uses IP) to be re-written and replaced.  This would
be hard enough with current equipment, but what about legacy kit where
the manufacturer has gone out of business? (think of older jet direct
cards, still working happily).

My networks (Home and Office) are both dual stack, running both IPv4 and
IPv6.  The IPv4 is on 192.168 ranges while the IPv6 is fully routed (see
http://wellsted6.uk.to or http://goldthorn6.co.uk if you have IPv6).  I
suspect the first move by ISPs will be to double NAT (i.e. the outside
address on your router will be in one of the RFC1918 ranges either 10/8
or 172.16/15 while you use 192.168/16 on the inside).  This will open a
huge can of worms as many things will/may stop working (e.g. IPSEC VPNs,
VoIP (SIP hates single NAT enough already)).  I have the outside address
of my networks as the primary MX for the domains I administer, that
would have to stop with double NATting, so it would be back to relying
on POP3 from my ISP. Also you could probably say goodbye to fast
bittorrent (although ISPs might say that was a good thing).
