Ah, I think I get it. You're saying we should keep content locked up in Flash indefinitely because you don't believe that a better solution can get the penetration of Flash? Is that right?
The CDM API should make porting to multiple platforms easier because the browser implements all the non-DRM infrastructure like networking and playback. That said, I don't really expect Linux to suddenly be a top priority for Netflix or Amazon. On the other hand, a CDM is bright red bullseye for crackers. :)
