Irrelevant strawman.  Multicast delivery is a fundamental property of
almost every subnetwork layer, and the technology already exists to
make one-way ``broadcast-style'' multicast scaleable across the
wide-area network.  (Indeed, one can actually *buy* this service, for
corporate communications, from multiple ISPs.)  The bandwidth cost of
a single stream of audio is epsilon.

We've been able to do this in my Lab for almost a decade now -- we're
just waiting for the commercial networks to catch up.
