A few years back I also used WebRTC with different backends (Kurento, Puppeteer, Mediasoup) to try and make an audio-based social network. I got pretty far but I was on my own and a grad student at the same time so the project died. A few years later Clubhouse became viral, it was essentially the same thing I was doing. I still use WebRTC for my personal projects but the difficulty of compiling and embedding it in a backend makes it really hard to use by the masses. My next project is going to use Pion, and I'm going to make a static compilation and just distribute the executable and have the main service use IPC to communicate with the Pion module.
