I had the same question. I found Miyakawa-san's presentation has some dramatic examples of CGN NAT444 effects using Google Maps: http://meetings.apnic.net/__data/assets/file/0011/38297/Miyakawa-APNIC-KEYNOTE-IPv6-2011-8.pptx.pdf However these are with a very high address-sharing ratio (several thousands users per address). Using a sparser density (<= 64 users per address) is likely to show much less dramatic user impacts. /JF
