This looks interesting but what default stun and turn servers are you using? I've tried to get webrtc to work before and it always failed without a TURN server (relay)
So... p2p file sharing over webrtc over nostr is here. This is the PoC.

Will share a hosted version that you can seamlessly use soon, we are still better-ing the UI.
Also we might not want to fully commit to a hosted version because I dont want to handle DMCA and CSAM complaints, and i cannot commit to a moderation UI at this moment. We will however try to make the open source code as easy to run as possible.
The Readme is the spec.
Thanks to nostr:nprofile1qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcprpmhxue69uhkv6tvw3jhytnwdaehgu3wwa5kuef0qqs2ytd7283uwxdd3vkdc0j0lsshdusrw0esy7m858wxcm5hd77ddkqc0epzd who's shared my excitement about being able to build this and contributed code to help make this real.

If both peers are behind NATs you WOULD need a TURN server. Thats the only way as we understand it, one upgrade that could be done is to fallback to the ToR network if a direct route cannot be established, but that would suck for bandwidth
