The Keybase folks should seriously consider getting in on this. There are not many groups I'd trust to design something cryptographically sound and friendly enough to be useable (both for citizens and the government - you need at least two tiers so WHEN the inevitable private key leak happens on the government's part, it isn't the master key kept in cold storage).
