An interesting assertion. I'd agree on the ISP NAT part. Not sure about the
"other form of global address sharing" part, since single NAT is address
sharing. Do you have any data?
IPv4 free pool runout simply means connecting to the Internet is going to
get more expensive.
No, it means it is going to require double NAT unless providers deploy IPv6.
I've been told on numerous occasions that multi-layer NAT will significantly
increase opex.
That is the message that needs to be got across.
I suspect your message will result in a response of "Double whasis? I can still
get my pr0n, right?". I'd imagine a message that says "you're going to end up
paying more for your pr0n" will get more people's attention.
