Tree Raves: A Case Study in Social Protocols

Here in Cambridge, MA, a friend used to host silent disco parties by bringing a small low-power FM transmitter connected to his audio playback device. He’d hand out small FM receivers & headphones, but people could also bring their own (in those days, most portable audio systems included an FM radio receiver).
Bluetooth is so flaky that I couldn't imagine a solution that would work for ~30 connections.
They are commonly used for pentesting, hacking, and Wi-Fi mapping.
I do agree though, the useage of Spotify as a given is annoying. Especially since everyone will never be perfectly synced up. I remember silent raves, back a decade ago, would use a FM transmitter mixed with cheapo portable fm receivers.
