NAT can be a pain in the backside. try debugging network problems when
there's a NAT machine in the middle. (now was that /my/ packet?  
maybe....).

NAT often requires knowledge of user protocol in order to function, 
(eg FTP).

NAT only works one way. (breaks peer to peer addressing).

i'm sure there's plenty more reasons, but i just cant think of them. i 
dont think NAT is /bad/, i just think it is a workaround.

globally unique addrs, eg with IPv6:
	- disadvantages none

NAT:
	- advantages over 'global unique addresses' none
	- disadvantages some

so where's the argument?

ok... i've got a web server running on my desktop,
dunlop.dub.ie.alphyra.com. connect to it. (ok you cant resolve the
adderss, but even you could, it wouldnt help).

so when everyone is using IPv6, they should still use NAT?
