i don't think that's a realistic proposition unless you intend ford and
wal-mart and others with big enterprise-wide ip networks to use NAT when
connecting their desktops. some of these people use direct peering in
addition to transit-provider-of-the-month, and that's a good model for
overall internet growth and robustness.
