The way I see Mailpile becoming popular and putting a dent in dragnet surveillance is not by everyone downloading it and running themselves but a trusted third party running it and holding keys for a relatively small group of people. Some will complain that this way the third party can still access the key and mail encrypted for it. That's true but also a massive step up from everyone on the wire being able to read your messages. Now, an intelligence agency can just siphon anything and everything. With a large number of independent e-mail providers, only narrow and targeted surveillance would be feasible. All that without giving up any convenience of webmail.
