Serious question. I'm in my mid 40s, I've been using Linux for over two decades. I use a tinc network (also Syncthing) to manage my home and two offices, plus my kids laptops. We do gaming, I do media server stuff. I teach IT, I own a (presently inactive) web-design company..etc. etc. All to say, I don't understand the point of this. What is this for and why would I want it?
