I thought that at a bare minimum, you needed public IPv4 addresses  
for the NAT gateways and any public facing IPv4 services.

In the ideal world, everyone would run with the latest gear.   
However, pragmatically speaking and as you might have seen on NANOG  
regarding discussions about MSFC2s and Cisco 7600 series routers, few  
of us live in the ideal world.

The reality is that there is old gear out there that can't be  
upgraded for one reason or another.  This will continue to be the  
case.  A prudent course of action would be for folks to take an  
inventory of their equipment and software systems and perform triage  
( to figure out what's hopeless,  
what can be fixed, and what is OK.  Once this is done, people can get  
an idea of what they're in store for when IPv4 address space is no  
longer available via traditional means.
