Mac OS X 10.7, still no DHCPv6

In some environments that's a feature. :)

Also, I think people forget the original motivation behind privacy 
addresses. If you use RA/SLAAC on every different network that you use 
IPv6 (say, with your laptop) then the bottom 64 bits are always going to 
be the same. The theory was that this could provide a way to track the 
same user across multiple networks, thus the desire to have the ability 
to generate host identifiers that are "unique-but-temporary."

If you're on your home network (where the network prefix is always going 
to be the same) privacy addresses have limited (although non-zero) 
utility. If you're at work you're subject to the policies there, and if 
they say "dhcpv6 + no privacy addresses" then that's that.
