Yeah, xmpp is a great protocol, but everyone needs to be in the vicinity of the server. A mesh network (p2p) where every client also relays messages for other clients is better suited for this usecase. I think meshtastic is an open standard for this. Briar is a valid alternative that works with phones, which most people already own. Not the greatest idea to bring those to protests, though because of network surveillance attacks by police forces. A meshtastic device would solve this problem.



This could be really useful and looks very promising already. Linux is missing a tool like timelimit.io on android to restrict my kids usage of their desktops. The planned idea to put several programms into one usage category would be essential to make it work.
