This is all good but the biggest thing right now is that there is no coordinated effort to build a system that's easy to use, secure, and open source. Everyone can spend their time working on their own solution but no one would use it as everyone's work will be incompatible with each other. This means no one (or rather, not enough people) will use any solutions that are developed and revert back to something like Skype, FB message, etc. I think what we need is to establish a foundation that coordinates the development efforts for these secure and reliable software packages with a few centralized projects that become a standard (here's hope for WebRTC).
