I don't know exact requirements and application used, but given IP TV
deployments relying heavily on multicast, and all other "VoD"
technologies also using multicast...I find Your comments disturbing :)

However, if you don't control the network over which it will be
transported, you need to replicate each stream...and so either
you'll find bandwidth to do it (or pay for it) or be forced to switch
to other design.
