=> I changed the "Mac OS" into "Apple OS X" (IMHO Apple is redundant
but perhaps not so as the old name is still used :-).

=> the main issue in the previous attempt is to pas the decapsulated packet.
In fact not only the whole packet with the DHCPv6 relay stuff is required
but some extra infos are needed too: the receiving interface and the
IPv6 source/client address.
BTW Unix sockets are again the worst solution. For ISC DHCP I used a
pair of UDP sockets bound to the loopback. As I explained in this list
we can use the same format and transport so be able to develop both
sides (DHCPv6 and DHCPv4) in parallel...
A final note: it seems the same format should be used in both way,
i.e., in DHCPv6 -> DHCPv4 and DHCPv4 -> DHCPv6. And TWO sockets are
needed if you don't want to read what you've just written.

=> a bit short and BTW I didn't see any contributions...
