Old joke, "Netflix works GREAT on Linux, get a Roku box."
So "Netflix on Linux" is really 'NetFlix on a Linux running on a Laptop.' But here is the reality, if you make a list ordered by how many people would benefit of things you could put a Netflix client on, "Linux based laptops" would be nearly the bottom of the list, right above the Chumby. But if you made a list of "things we could do to irritate skittish big-content types" putting out a Netflix client on a Linux based system would be at near top of the list. That is a killer combination that I doubt will be dealt with soon.
