With all that bitching about IPv6 how come nobody wrote an RFC for a very 
simple solution to the IPv4 address exhaustion problem:

Step 1: specify an IP option for extra "low order" bits of source & 
destination address.  Add handling of these to the popular OSes.

Step 2: make NATs which directly connect extended addresses but also NAT 
them to non-extended external IPs.

Step 3: leave backones unchanged.  Gradually reduce size of allocated 
blocks forcing people to NAT as above.

Step 4: watch people migrating their apps to extended addresses to avoid 
dealing with NAT bogosity and resulting tech support calls & costs.

Step 5: remove NATs.
