For a good chunk of people it is still the cable companies that provide the last-mile pipe that something like this requires. And because they control it they can skew the bandwidth allocation towards their own digital TV side. You never hit a Comcast bandwidth cap by watching too much cable TV. But you can quite easily hit your "unlimited" bandwidth cap on the same pipe if you stream too much video over that very same cable prompting nasty email warnings and eventually termination of service. I don't see how BitTorrent Live addresses this in any way.
