Good idea. Would like the ability to click on a file and know how many cities it's copied in. (This is the weakest point of all your competition. They pretty much don't tell you.) And then click another button to return the hash on each of those copies. Perhaps the ability to verify all data once per day or once per week would also help. Of course it would all be encrypted before upload, too. (Oh, and beware that file sizes can sometimes imply content, so you might have to randomize that somewhat prior to upload. Uploading the same file twice in a row should create different amounts of traffic and completely different data payloads.) Also, there should be a one-time paid "insurance" option to force the data into readonly mode if for any reason your payment method fails. Google does this for free. Others just delete everything after a few months.
