Netflix could too, if they can get authorization to actually use the system (insert MPAA members howling about their IP being on a P2P network
I can see the MPAA accepting "partial" distribution (say, 75% or maybe even 90% or 99%+ of the bits) over hard-to-track torrent-like protocols as long as enough of the bits are distributed "directly" to ensure that those having only the "partial" distribution either get a useless (e.g. encrypted or compressed-with-key-bits-missing) bits or they get bits that result in such an unpleasant viewing experience (drop-outs/noise, segments that have key plot elements removed, or missing audio) that it won't be an economic threat.
Heck, if the recording-industry was smart, they would set up their own "stripped-to-the-point-of-useless" torrent-like system then invite customers to buy/rent unique-per-customer versions of the missing data. Of course there would have to be some incentive/compensation for your average viewer for them to allow others to "upload" from their computer, such as "fan bucks" usable at the movie's official web site online store or some such.
From a marketing perspective, it would also be smart for the recording industry to use existing BitTorrent-type networks to seed sample TV episodes (complete with ads of course, sigh).
