i think that as with dotcomenomics, we're expected to grow our way outta this.

yes, it is.  but from a policy standpoint, that doesn't matter.  we're going
to run out of new ipv4 soon, and there are three ways to jump:

	1. stop growing the network
	2. dramatically increase NATism
	3. use IPv6

of the three, i like #4.  of the three we actually have, though, i pick #3.
