Mac OS X 10.7, still no DHCPv6

The documents are done, but, I would argue that neither provides a mature
set of features.

Yes, they've (sort of) resolved the DNS server issue for SLAAC, but, that's
recent and getting it into vendor support will be nice. The lack of NTP and
certain other options in SLAAC is still a disappointment and I would
argue that a fully matured SLAAC process would include a mechanism
for specifying extensible choices of things.

For DHCP, the lack of ability to deliver routing policies or recommendations
through DHCP is a roadblock for some deployments which is still in place
in the documents and should be fixed to produce a mature implementation.
