I would love for Netflix to produce a Linux client (I was outraged to find there wasn't one), even though Netflix Canada still does not have anything to watch on it, so I'm paying $8 for about one movie every month.
Unfortunately, there are simply too many distributions to support. If we pay hard earned money for something, we demand that it works always, regardless of the distribution we may be using or what else we are running.
Saying that, It would be a joke to write a Linux client, especially since they already have some experienced developers as it would seem. I imagine there may be some lobbying that is keeping the service from coming to linux. Imagine the concept of dirt cheap netflix set top boxes using embedded linux. It may even be pretty easy to make with a wireless arduino module. I imagine it would completely destroy cable distribution as we know it (not that it isn't already dying), in America at least. The fact that most people still want to watch their tv on a tv, instead of having to hook up their wireless laptop to a wired tv to stream online media. If viewers could pay 10 dollars once for a set top box and 8 dollars a month for netlix, instead of 50 for cable, and a lot more for a crappy pvr. Imagine a set top box that is just a sheva plug using external flash storage, so you tv could go with you everywhere. I know I am a a dreamer. Linux opens too many possibilities.
