Thanks for your work -- I've used pion before myself.
Then you know the answer to that question. I imagine on a thread like this that would only tread the surface of the complexity, the first question will always be "What the hell even is STUN, TURN, ICE, SCTP, DTLS, SRTP?"
And thats the beginning of the complexity. But it's also a naturally complex problem. So, I thought it was a joke.
I have have been trying my best to make WebRTC more accessible [0] [1]. It's powerful, but the complexity makes it challenging.
