IMHO, the biggest barrier to IPv4 SSM deployment is the requirement that 
edge IEEE 802 switches be re-engineered to understand a new kind of IP 
packet: the IPv4 IGMPv3 packet.

IPv6 suffers from the same problem; to wit, that IEEE 802 switches have to 
now be re-engineered to interpret IPv6 MLD packets.

Fix the unreasonable IGMPv3/MLD requirement for nominally IEEE 802 
switches, and I'll bet you dollars to donuts that SSM will take off like a 
rocket.
