Don't just take the simpleminded approach of taking existing data and encrypting 
it. Develop new encryption friendly protocols that aren't excessivly chatty to 
begin with.

just like IPv6 is going to eliminate all firewalls and NAT and restore the 
pristine end-to-end Internet that was originally designed?

sorry, but I think those days are past. The Internet isn't A International 
Network, it's a Network of Networks. While I agree that the core that connects 
the edge networks where the servers and users live should be data agnostic, the 
points where the networks join is not going to be transparent as the owners of 
the edge networks have not only a right, but a duty to manage their network. The 
interesting discussion is how you define core vs edge (I count ISP networks as 
core, even if they have some islands inside them that count as edge)
