A percentage that are making use of their public IP for inbound
traffic? Yes. However, what percentage is that, and what fraction of
them are actually "dependent" on it? I'd venture to say that the vast
majority of consumers that have a port mapping through their home NAT/FW
device are using it for gaming and/or P2P, both of which violate most
ISPs' AUPs anyways. Still, those are a tiny fraction of the overall
population, most of whom are still trying to figure out how to use IE5
and don't have a clue what a "public address" or "port mapping" is.

And, from the perspective of most monopoly or duopoly providers, that is
an opportunity to "upsell" them to public IP service, just like the
thousands of irate phone calls they get today about being given a
dynamic IP address are an opportunity to upsell them to static IP service.
Also, at the same time those customers would be moved to NAT or NAT-PT
for IPv4, they could be given public, static IPv6 addresses for free, to
use instead of public, static IPv4 addresses.
> Now, this does not mean that they couldn't do a gradual switchover, I agree. But I don't agree that it is for us to force them to do it.
On that, we agree. However, it is not "us" that will be doing the
forcing but rather IPv4 exhaustion, caused by the victims' own consumption.
