Tox - A new kind of instant messaging

This is tox an instant messaging system that is supposedly more safe and secure against spying etc in times of all those scandals.
It is free software and does not rely on servers, so the main problems most chat systems have are already solved.
I tried it out and it looks fine, but hard to find friends who will use it, so I don't have much experience with it, but it's worth keeping track of as an alternative to skype etc.
