Having read Tristans description of how VOD works it got me thinking. Would it be possible to supply the normal digital channels using the same method as VOD but without the pause, rewind, etc. that VOD has? That is just transmitting the live pictures from the selected channel to your TV. At the moment all 200 or so channels are sent to every STB taking up a hell of a lot of bandwidth. If only the selected channel was sent to your STB from the headend or hubsite there could be plenty of bandwidth available for other uses.
