Popcorn Time though goes against the principles of distributed network like BitTorrent. I.e. it prioritizes first data blocks most and as such it's not network friendly, since network is built on assumption of equal prioritization. So while it's an interesting idea in general, it doesn't sound like the right solution technically.

Anyway, it's going a bit off-topic here, except may be it's a good reminder that DRM should never be used since it only punishes legitimate customers and does nothing good.
