What is missing is an adaptive client (be it flash, or HTML5) which will
transparently use multicast if it's available, and otherwise fall back to
unicast.
I've discussed this many times with IPTV technology providers. Many have agreed
that it's a superb solution, but none have delivered.
Delivering multicast to end users is fundamentally not hard. The biggest issue
seems to be with residential CPE (pretty much the same problem as IPv6,
really).
