That's not what it was created for. It was created to protect dying business models and to force end users to continue to purchase 'rights' to the same as many times as possible.
While I'd like the option to have Netflix on my Linux HTPC, I don't think DRM on Linux is feasible. In order for DRM to be effective, it needs to effectively control the entire system. The problem is that so-called 'content owners' are not the boss of my Linux machines: I AM.
So, if there's a way to have some kind of self-contained DRM on the system that doesn't get in my way and only deals with Netflix, that's fine. However, if you think someone won't circumvent it in about 2 seconds flat, you've got another thing coming.
And, I think, that is where DRM on Linux is not feasible at all. While DRM can argue it's need is greater than yours (not well, but it has succeeded with the yo-yo OS), it cannot argue that with the other content creators on your system--namely the OS writers/contributors. The sheer number of people/organizations require to come into agreement for such a thing to be possible is staggering.
I don't think it is possible.
