Someone should set up a big fat pipe right outside of Amazon data centers with free unlimited transfers, get data on behalf of customers copied to hard drives from AWS, and then attach those hard drives to the Uber pipe. I bet that service could work for a short & glorious moment in time.
A flat fee for the act of a human getting the data onto the physical medium ($200) + the cost of shipping (<$100?) + $15 per day you keep the snowball device past the first + price per GB of data you're transferring ($0.03 per/GB).
So if your getting out 30 TB of data that's $200 + ~$100 + ($0.03 * 30000) = ~$1200
