[mivplzub] Torrent synchronized with TV

Create a Bittorrent client that will seed a file gradually, not making all the blocks available at once.  The expected use case is officially broadcasting over Bittorrent a prerecorded television program in synchrony with the television broadcast. There is the slightly tricky problem of lining up byte positions in a compressed video file with the progress of time within the video.

Being the first torrent, it will likely acquire the largest swarm.  This official torrent could include commercials encoded into the video.

We also need a client able to play partially downloaded videos, as if streaming.
