Re:VoD ? Multicast (Score 1)

Multicast will not solve the Video on Demand problem. Your description of the bandwidth problem and your definition of VoD is very good. I believe real Video on Demand most likely will be made possible by using a caching system somewhat similar to todays web-proxies and caches like squid,etc. I know several people within IETF and TERENA are working on this already. But as you, I belive the future will bring both multicasted "broadcasts" and pure Video on Demand. I think of a system similar to todays Icecast with multicast, capable of streaming video. And a network of local media-caches keeping unnecessary traffic off the common Internet backbone.
