Time to start thinking a little further down the line.  What if the phone
actually becomes an wireless IP gateway router?  It routes packets from a
PAN (personal area network) riding on top of Bluetooth or 802.11{a,b} to the
3G network for transit.  NAT would certainly become very messy.

*nod* NAT is a solution for current problems, in some situations. It may or
may not create more problems in the future than it solves in the present
(sign me up for one of those gateway router phones though - mmm...)

Again, while I'm not predicting what kind of network landscape we may see in
the future, NAT _does_ appear to solve problems in the present under certain
situations, and IMHO should not be dismissed out of hand just because it's
not "pure IP."

Forward thinking is critical - but those who do it at the expense of current
issues are called researchers and scientists, and generally are not running
production networks. :)
