The second problem is that judges won't look kindly upon any attempt to blind yourself to what's going on. You'd be a lot better off making a good faith effort to comply with the law, even if you're not perfect at it. Otherwise, people will see it as a wink-and-a-nudge kind of thing, which is exactly what you don't want if you're trying to run a legitimate business.
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"
