Using the latest dev/unstable version of Chrome (v38+), linux users can now watch netflix without the need to faff about installing silverlight/pipelight.
This is because Google, MS and Netflix have apparently been working on HTML5 extensions which satisfy content providers with respect to DRM.
If using linux, you still need a custom user-agent string, and you need to set your Netlfix prefs to use HTML5, rather than Silverlight
Details here & I can confirm it's working for me under Arch linux, using "chrome-chrome-dev" from AUR: https://plus.google.com/104912707432334684242/posts/1gnbmo63xVa
ps: now if we can just convince Lightbox to ditch Silverlight, or at least offer an HTML5 option....
