A simple comment to share Jitsi[1]. It uses XMPP but also many other protocols. It encrypt text/audio/video and even have a share and control screen feature. I discovered it Friday. Our team will certainly use it as a secure replacement for Hangouts and Skype. My only complain is that it doesn't use my already existing gpg keys. [1]: https://jitsi.org https://jitsi.org
