Doug, your assumption about how radio on the net works is also incorrect, because each user is initiating a non-simultaneous transmission of the same content, just to them. Even in circumstances where sharing bandwidth is possible in principle, you need multicast to make this happen. I won't repeat my previous email here. Multicast and MOD are different. MOD is the view of what the user is doing. Multicast refers to how the network and different servers handle this user request. The key point here is that bandwidth demands are exploding (around 300% a year), and operators will be using every technology they can to expand the effective bandwidth, and that includes using efficient compression algorithms, even once multi-cast technologies are in place. No industry has ever seen this kind of sustained growth in demand and performance, and managing it is not a small undertaking.
