Goliath needs to get stoned, it's been a major hurdle in doing IGMPv3/SSM because of the locking fandango. I look forward to it. [For those who ask, what the hell? IGMPv3 potentially makes your wireless multicast better with or without little things like SSM, because of protocol robustness, compact state-changes, and the use of a single link-local IPv4 group for state-change reports, making it easier for your switches to actually do their job.]
