Thanks for that informative answer.

So we have a serverless web-chat with a stun-server that might go offline at any time.

I don't know a solution to do the chat really serverless. One option would be to use ethereums whisper, so we can use all eth-nodes to handle the webrtc-connection. This would not be 'really' serverless but at least surely work for a long time.

Ethereum is trying to be a lot of things and has some pretty severe architectural problems. I bet the Mozilla stun server lasts longer.

Exactly, how is STUN not centralized in this solution??
