Imagine every high school and tertiary institution in the world ran a conversation and media-sharing servers for its students. With sign-ups only available in person, and staff taking responsibility for admin and moderation, and training interested students to assist with those tasks.
They could use a modified version of fediverse that somehow federates only with other schools' servers. But it would be intriguing to see if they could manage it safely with open federation.
