Ask HN: Interest in self-hosted secure messaging system with iOS/Android apps?

I want to gauge the interest in a new open-source project for a self-hosted secure mobile messaging platform. The emphasis of this project is making it very easy to deploy (e.g. 1-click deployment onto EC2 micro-instance) and use with your network of friends.

High-level functionality

- Messages encrypted on client and sent via HTTPS to server. - Messages deleted from server as soon as recipient receives message. - Mechanism of locally sharing a private key between devices (e.g. Bump like functionality if you want to get fancy) - Clients receive delivery and read confirmation (and possibly see when other person is typing)

End-product

- iOS / Android apps available in respective app stores - Backend available on AWS Marketplace for 1-click deployment - Source code for mobile apps / backend available with instructions on how to build / deploy

Implementation

- Focus on simplicity that’s easy for others to audit - Backend in Python or PHP and MySQL
