You can stop reading here if you like, but one of the things that prompted
the question is this:
I read an interview with itojun, and he said that he thinks people are
wasting their time using NAT (he says IPv6 is a simpler solution). But if
IPv6-only doesn't allow communication with IPv4-only
Apache have failed at
run-time (some parts of the ABI change, mod_ssl doesn't
cope).
it is rumored that someone (outside of KAME) has IPv6+SSL patch.
