I'm emailing this first because I don't always have good success with communication.
A messaging system is needed with the following properties: - sneakernet/airgapped cryptography - immutable preservation of public discourse - support/preference for anonymity - integration with or expansion of one or more systems that are already in-use, with one or more existing development and user communities - peer to peer, disaster-ready - cryptographic delivery (and/or read) receipts - simple, clear reimplementable and third-party-maintainable design, making heavy reuse of few basic parts Although some of the above properties are common, some are very rare. The rare properties should be prioritised.
