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.]
