Of course we all "know" that DRM is fundamentally impossible, but there is a qualitative difference between trying to do DRM on a proprietary platform and on an open platform.
Edit: $60, my bad.
The reason Moonlight cannot play with Netflix's standard player, by the way, is that Microsoft refuses to license its DRM component for desktop Linux use. Moonlight runs the player on embedded Linux devices just fine, but since Linux is still small enough that MS can get away with slighting it, and since it benefits Windows to keep Linux as incapable as possible, they refuse to allow non-embedded Linux systems to run the module.
Frankly I'm surprised that people haven't cracked the MS DRM just out of spite for this move.
Because it's not worth it. People that want to pirate simply leech the movie off some torrent, instead of cracking a DRM then still paying for it.
