	er... what part of dual-stack didn't you understand?
	dual-stack consumes exactly the same number of v4 and v6 addresses.
	
	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.
