It is possible to watch netflix on Linux natively. WINE is a binary compatibility layer that natively runs windows binaries on POSIX environments such as BSD variants, Linux, and Darwin. There is a set of patches that allows you to install silverlight 4 in WINE. After this, you can install FireFox (windows version) to utilize the plugin. This will give you a browser that runs at native speed and capable of streaming netflix. Here is my reference...
If you're running ubuntu 12.10, there's a PPA and installing it is as simple as
sudo apt-add-repository ppa:ehoover/compholio
sudo apt-get update && sudo apt-get install netflix-desktop
Otherwise you may need a patched version of wine to run the windows versions of firefox and silverlight.
The site is for Ubuntu users, but I myself am a debian (compiled from scratch) user and have gotten it to work by patching WINE manually. With a little searching on google, there are people that have gotten this to work on other distro's such as Fedora and Arch. By reading their tutorials, this might help users of similar distro's get this running or compile binaries for distro's such as mageia, mandriva, slax, slackware, and gentoo. Good luck with Netflix, and keep me posted if you find a way to use the silverlight plugin with a rekonq =)
In addition certain ARM platforms have a built in hardware DRM implementation called TrustZone into the SoC design. This allows developers of ARM boards (such as mobile android devices, and Roku) to stream netflix on top of a Linux based operating system.
