When IPv6 offers something end users or ISPs value over IPv4+NAT. Hah, interesting thought! :-) Perhaps we should push for people to use the IPv4+NAT kludge,
A very large number of folks are using IPv4+NAT now, mostly without complaint (or even awareness). I use it myself quite frequently. In a limited (albeit typical) mode of communication, NAT works just fine. IPv6, on the other hand, does NOT work for the vast majority of people on the Internet.
Two seperately NAT'ed hosts don't communicate enough today for more than a "priviledge few" to discover all the issues with it.
You are expecting people who have been trained to expect to have to reboot periodically and/or reinstall entire operating systems when they have problems to get annoyed when they have difficulties trying to communicate to a remote site because of NAT? If/when folks run into difficulties due to NAT, I suspect they'll just shrug their shoulders, mumble something about broken web sites, and fine another porn^H^H^H^Hcontent site that works. Rgds, -drc
