The problem is that there is no DHCPv6 for the Mac (well, I suppose I
could try building it by hand and see how far I get). I'm pretty sure
that Macs aren't set up to do a layer 2 bridge group between their
interfaces, and moreover I think this is risky behavior in terms of
creating a loop if something goes wrong on the laptop even if the host
OS supports it.
