Unfortunately, it doesn't work. Moonlight 2.0 has most of the features of Silverlight 2.0 that Netflix uses...except for the DRM support...which means it doesn't work. Makes no sense to me, since the Roku works just fine and it's Linux-based.
..and yes, I forgot about it when I wrote my first post, but that's another reason my HTPC will probably have to be Windows-based.
BTW, just tried it, and this is what you get. So, even if Moonlight 2.0 did support all the necessary features, Netflix would still block it. ...hmmm, I wonder if I spoofed my browser agent...
EDIT:
Tried that...got this.
