Launching a filehosting site that is end-to-end encrypted at the browser and using 3rd party nodes for the file hosting without being a torrent network sounds revolutionary, at least to me. By providing the encryption keys that only the user owns is helping to stay within the DMCA Safe Harbour. In that case the legal issues of the content are the concern of the user, not the service provider. Please correct if I'm wrong.
