	so... just how -much- of the net today is behind
	nats?  20%? 80%?  99.8%  --- and can those networks	
	be said to be on the net in any realistic sense?
	(ok, pragmatically you can make that argument, that
	nats/algs are just another gateway linking up disparate
	bits of infrastructure and i'll likely believe you)
	but i'm not sure if you are talking the count of 
	protocol stacks behind ALG/NAT boxen, or subnets behind
	ALG/NAT boxen.  and as far as the ASN boundary btwn BGP
	speakers is concerned, do we need to care?
