I think you're partly right, Kevin, but your objections to VOD over HFC apply doubly so to satellite and terrestrial broadcasting (no splits and no return path *at all*). ADSL 2+ (and no doubt follow ons with even higher bandwidth) is still futureware in many ways, and obviously a large-scale roll out with thousands of people viewing VOD events in an area has colossal demands on the back-end kit (in a way, the protocol and the kit in the home are the easy bit).

So VOD over HFC is about the best we're going to get in the near future, but it's not going to supplant conventional broadcasting any time soon. After all, splitting the network down, if taken to its logical conclusion results in each house having its own feed back to a central point, which is effectively a copper pair or FTTH.
