This requires a more precise definition of "IPv6 only". If it means
"Only IPv6 on the devices and absolutely no access to a dual stack
friendly machine", yes, I agree with you as far as Internet
connectivity is concerned (there are IPv6-only networks in production,
in closed environments, where access to the Internet is not required).

However, if you change the definition to "Only IPv6 on the devices but
there are 1 to N dual stack friendly machines, willing to proxy",
then, it may work and it may be the only solution for the typical
African university (last time, I checked, the Cocody University in
Abidjan had only a /28 for its 10,000 students...).

I installed such a setup recently, for a training session in
Nouakchott, there was only one machine with a dual-stack and a public
IPv4 address, running BIND as a DNS recursor, Apache serving as a Web
proxy, etc and everything worked mostly fine. ALGs are great.

I was quite happy with 646 at the IETF in Philadelphia.
