Hmm, looks like:
- have a sysctl to change system-wide behavior
- have a setsockopt to change per-socket behavior
- default value for sysctl is still under debate. I vote for "off".
matt, do you have any specific symbol in your mind for setsockopt?
(kame/freebsd3 uses IPV6_BINDV6ONLY, which disables RFC1933 special
behavior when set to 1)
