absense of multicast deployment

By everything I can tell, it's roughly about 10% for global  
deployment, see


and is becoming basically BCP in the enterprise IPTV environment  
(which are currently all
"walled gardens"). (Note that this deployment is effectively entirely  
ASM / IGMP v2.)

By any measure, multicast deployment is much larger than IPv6  
deployment at present, and it is growing.
I will be glad to argue the point to any length you might desire.

Of course, the deployment did not exactly take the form that was  
anticipated in 2000...
