Merchant acquisition is the hardest part of a payments startup. Tipjoy failed to get the top "merchants" on Twitter's platform to use us. That's because they didn't really want to make money. Look at what tweetdeck, twitpic, seesmic, etc. still do today with commerce: nothing.
There is a lot more to do for minno, but the micro sites are great.
That said, I'm not sure how letting people download it from their servers is any better than sending it on a DVD, and an envelope full of enough DVDs has a much higher bandwidth (and a much higher latency) than most internet connections in the USA.
If anything, the fact that a human would probably have to handle the DVD to put it into the mail would be a better copyright filter than most programs. "Oh, hey, this is that new movie. Nice try. tosses DVD into trash"
Can you offer the download in some format that lets me resume? Perhaps a private torrent of some kind? Then you'd have a customer in me.
If I can't download the file within 24 hours, it is gone?
People will immediately use your service to download "illegal" content, aka movies and tv shows, and then download from you to themselves. How do you plan on responding when the government comes a knockin?
Beyond this, I love the entire concept. Its a novel business idea and exactly the kind that the reprehensible trend towards copyright restriction is going to snuff out.
