In DHCPv4 we've had no end of problems because of standards text that
touches into the IP and link layer headers (all-ones limited
broadcast).

So it would be my vast preference to maintain a setup where raw
packets aren't required.  I think this means the client supplies the
MAC address as an option inside its IA_*'s, as part of any "final"
solution.

An alternative interim solution in that area would be to use the
client's link local address as it was perceived by the relay agent (or
by the server directly).  Relays and servers already record this so
they know where to direct the replies.

You'd just need to decode the EUI-64 (or encode it from a known MAC
address).
