Nice.

er... what part of dual-stack didn't you understand?
dual-stack consumes exactly the same number of v4 and v6 addresses.
I would expect the number of v6 addresses assigned to a host to be a
multiple of the number of v4 addresses, depending on the type of host.
if you expect to dual-stack everything - you need to look again.
either you are going to need:
lots more IPv4 space
stealing ports to mux addresses
run straight-up native IPv6 - no IPv4 (unless you need to talk to
a v4-only host - then use IVI or similar..)
imho - the path through the woods is an IVI-like solution.
Or, dual stack today. When you've run out of IPv4 addresses for new end
users, set them up an IPv6 HTTP proxy, SMTP relay and DNS resolver and/or
charge a premium for IPv4 addresses when you start to sweat.
