Well...unless one calls v6 rogue RAs and the immediate resulting DoS a unicast v6 deployment bug.  ;-)   

Only mitigated by snooping/filtering at L2 which one could consider similar extra complexity to make unicast v6 viable.

Agree re: comments on IGMP v2/v3 as well as the consensus shift I read here towards SSM-only for interdomain.

I hesitate to abandon a tool such as interdomain mcast, just because of technical complexity.

That complexity might influence a solution, but the service need should be steering the car, not the other way around.  The need for interdomain mcast is admittedly low to non-existent, but like to think 1->many just hasn't found it's killer app yet. 

ASM is still up here for now, but just as Bryant Pond, ME was last to have hand-crank phone service, 

including party line service , perhaps we aim for that interdomain ASM trophy too.
