Is there something like the 'wall' command that works on an ethernet level?
Basically, a mechanism to send a message to all clients connected to a same LAN network?
I can't find anything online, but I'm sure something like this would have been widely used a few decades ago, right?

The other possibility that comes to mind would be wiring `notify-send` to LAN based email.
