Hence, how does the big name ISPs do their Video ON Demand? It's a very
interesting problem which I can see. SInce everything is VOD, click of a
button and things start to happen. How much of bandwidth can the ISP
actually send over to the DSL user? I can understand if they only send
it to a handful. What about 1000 users? Everyone wants to watch at the
_same_ time, then they can do multicast. What about Per Per View then??
How can that be achieved??
