I'm aware that multicast is used extensively for "closed enterprise" 
networks in the financial and media industries.  It seems to work well 
when a single organization is paying for the entire network.

My executive official came from that background, so I get why someone 
from that world would think multicast is widely used. Asking enterprise 
network sales people, they keep saying Yes, of course we support 
multicast.

That's why I wanted to hear from public Internet engineers if multicast 
was still viable on the *public Internet*.
