I'm not sure it's different dictionaries, I think you're talking past each other. Video on demand and broadcast are 2 totally different animals. For VOD, multicast is not a good fit, clearly. But for broadcast, it has a lot of potential. Most of the issues with people wanting to pause, rewind, etc. are already handled by modern DVRs, even with live programming. What I haven't seen yet in this discussion (and sorry if I've missed it) is the fact that every evening every broadcast network sends out hour after hour of what are essentially "live" broadcasts, in the sense that they were not available "on demand" before they were aired "on TV" that night. In addition to live broadcasts, this nightly programming is ideal for multicast, especially since nowadays most of that programming is viewed off the DVR at another time anyway. So filling up that DVR (or even watching it live) could happen over multicast just as well as it could happen over unicast. But more importantly, what's missing from this conversation is that the broadcast networks, the existing cable/satellite/etc. providers, and everyone else who has a multi-billion dollar vested interest in the way that the business is structured now would fight this tooth and nail. So we can engineer all the awesome solutions we want, they are overwhelmingly unlikely to actually happen. Doug
