Experimenting with WebRTC and Qt

✅ Strengths of the Protocol

Bootstrapping simplicity. ntfy.sh (a public pub/sub broker over HTTP) reused instead of running own signaling server — low ops overhead, very easy to test/deploy.
Connection uniqueness. Session ID namespace (mediaThorSendRecv_%s) ensures that two peers with the same session ID are mapped to the same SSE channel.
Each peer has its own GUID, so can differentiate sender vs. receiver.
Role negotiation. The GUID lexicographic comparison is a simple, deterministic way to pick the offerer/answerer. This avoids “double offer” collisions.
Handshake (SYN/ACK). A minimal two-step handshake before starting WebRTC exchange prevents mis-parsing of random messages and gives you a clear synchronization point.
Message framing. Prefixing each message with the sender’s GUID + newline ensures you can distinguish origin and validate consistency across session.
