The plug-in is interesting, looks like it's operating as a proxy to the Netflix web page. We could do something like that, but it's friable: any time Netflix changes their page, we'd have to change our code too. I'm hoping for an API to call instead.
I've looked at the Netflix sounce code. I don't think their entire solution is open, just pieces, but I'd be very interested to find out I am wrong...
