People may perceive value, but, I truly hope that they won't be able  
to obtain the "functionality".  It's just a very bad idea that does  
terrible things to the network. NAT/PAT was a necessary evil in IPv4  
to extend the lifetime of the addressing until IPv6 could be almost  
ready. It should be allowed to die with IPv4.

Sort of, but, yeah.  That's OK.  Unfortunate, but, OK.

I actually think that now that we have a transfer market policy, IPv4  
will probably die much faster than it would have otherwise.
