Indeed. n:1 NAT for IPv6 doesn't make a whole lot of sense (except possibly for topology hiding, but there are far better ways of doing that in IPv6). In fact, according to a recent presentation by Fernando Gont at LACNOG, "NAT66 is one of the most frequently-asked IPv6 features." (see http://www.gont.com.ar/talks/lacnog2010/fgont-lacnog2010-ipv6-security.pdf, slide 13)  Given this, I suspect you won't have to wait long.

However you're arguing with a "True Believer" who makes rather rash assumptions with limited data -- there are probably better ways of spending your time. I've already added him to my "delete unread" filter...
