+1.

I can't remember which conference but there was an interesting talk from a
MIT professor who was talking about the concept of virtual networks for every
person (IIRC gih was also a speaker) 'on the internet'.  In essence we'd be 
walking around with our own personal firewalls dealing with all the interactions
we'd have with the net.

Expanding the idea further to look at the concept of not just a network per
device but new networks for interactions between devices (even if they were
created and torn down within seconds) and those interactions with other
devices - it isn't the number of devices that killed v4 (though it didn't help),
it's the exponential rate of interactions we'll see coming that'll be interesting.

Which led me to a question i hadn't seen brought up here - does the v4 network
ever get turned off ?  Anyone brave enough to make some predictions for future
historians looking through mailing list archives ? :-)
