Not that I know of, but I've been hoping for a plan similar to yours, but I'd be willing for it not to be unlimited. I was hoping for something like $40 for 15 movies per month, which would be a little over twice as much as Netflix's 3-at-a-time plan for roughly the same amount of movies (in my case....I get anywhere from 12-16 a month from there).
I'd pay $40 a month for that for the added convenience of no long waits in the queues and access to something besides the 3 movies from Netflix that I happen to have at home.
I really hope someone does this soon. Unfortunately (using the 15 movies a month) $5/each adds up to $75/month, which is out of my price range. Yeah, I like movies....but not that much.
