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.The main problem with SSM in IPv4 is that ASM was already in use, and there aren't enough implementations/deployments of SSM yet. But v6 need not carry the same albatross of legacy mechanisms around it's neck. It's a chance to do things right from the start.
