If you want to do MAC addresses based addressing with IPv6, what I would
suggest is just allowing your router to respond to router solicitations
and letting your clients use state-less auto-config to configure
themsevles with EUI-64, MAC address-based addresses, then relying upon
DHCPv6 to issue DNS and search domain information only, not actual

That's what I do in the IPv6 environments that I manage.
