But it's not our server and it's not a single server. This is a way bigger deal than most understand. Relays are insanely simple and lightweight "servers".

Want to run a relay for your friends and family? It's smaller and lighter than a bitcoin node by far.

Want every participant in a group to run device local relays and only connect over mesh net or ham radio? Possible.

NIP-EE relay usage is very light and events should generally be considered temporary. There is nothing that needs to be archived or stored long-term on relays.
