Will NetFlix ever do UMDs?

Even before my groundbreaking purchase of a PSP, I'd long wondered if NetFlix would ever diversify and start supporting a UMD rental model. This is a year-old issue, but still worth considering, I think. Blockbuster has gone the route, and so has GameFly - but apparently NetFlix scoffed at the notion. Such would be a risk of sorts, when thinking about it, seeing as how the market's shifted after less-than-stellar performance for UMD sales and the rise in interest for HD-DVD and BluRay discs.

It would still be cool, though.
