It's not clear to me that there's a reasonable business case for MLD 
support, especially from the perspective of IEEE 802 switch vendors.

In particular, MLD snooping requires IEEE 802 switches to recognize and 
decode IPv6 formatted packets.  Due to the 2^96 : 1 mapping between IPv6 
and Ethernet MAC multicast addresses, I'm afraid MLD snooping will actually 
require flooding decisions based on the IPv6 group addresses rather than 
the MAC multicast addresses.

To me, that seems an awfully high barrier to entry.
