VoD is and will remain STB only to be honest.
The idea of people having fast P2P connectivity won't appeal to ntl as they like most other providers of their type want to be a bit more than just a dumb pipe bandwidth supplier, they like some element of control over what is going through their bandwidth.
In ntl's case if people all start doing P2P trading of tv shows it means potentially less TV revenue, and P2P VoIP means less telephony revenue, so there really is no incentive there.
Besides ntl's network will become more defined when they move to a deeper metro ethernet model which shouldn't be too far off.

Is the Comcast US deployment of deep ethernet into their cable system, Converged Regional Access Network they call it, but same thing deeper ethernet segmentation on network.
BTW The stuff about doing a CRAN stylie deep ethernet metronet meaning that you can with very little work upgrade to billions of megabits per second isn't the case
