I think this is sadly the truth.  There are some problems that can be solved by multicast, but I've seen the number of customer requests for v4 multicast go by the wayside over the years.  The only people that are generally interested are the conference venues for technical things, e.g.: RIPE, ARIN/NANOG, APRICOT, etc.  

Plus, conferences like NANOG have beamed the video back to some other site for fanout as well, for both unicast and multicast.

The problems at Layer7 and below are solvable with market forces.  They're all 8/9 issues, about the content providers wanting to be paid-per-subscriber/viewer.  They don't want to know how few people are actually tuned in at that moment in some cases.  I'm sure they want to be paid some fraction of that cost that goes to your TV Transport conduit provider.
