Having used webrtc in offline environments (host device broadcast a local wifi), I can say it's a royal pain to use without ice/stun/turn servers. I had to manually mangle the sdp packets to make it work because browsers would randomly decide they needed ip privacy (from the device they connected to by ip...) where they'd translate ips to some_hash.local and try to find a turn server. I tried hosting a coturn server too, but browsers would sometimes ignore it since it was a local address. Mangling the sdp handshake is reliable but feels pretty jank.
