The usecase we're talking about here would be using nostr for a private ish chat room, like if in have a small relay with 20 friends Or whatever... Could 'enter' the chat room by setting amethyst tononoynread/write from this relay for now.

On the front end the user wouldn’t even have to see or understand that the relays are switching. Just have a list of “my networks” and depending which one you select the app automatically switches the corresponding relays on/off in the background.
