Could you build this?
Partial A web UI with WebRTC data channels and calling can be vibecoded, but correctly integrating post-quantum cryptography (ML-KEM/Kyber) and compiled Rust-to-WASM Signal Protocol implementations for reliable P2P state synchronization is non-trivial.
What it would actually take: The architecture involves a browser frontend interfacing with a WebAssembly module compiled from Rust that manages cryptographic state (Signal Protocol double ratchet, ML-KEM). Peer-to-peer connectivity uses WebRTC with STUN/TURN traversal and local storage (IndexedDB) for encrypted chat history and state. The hardest part is correctly maintaining ratchet state across asynchronous browser environments without server-side message ordering or fallback message queues.
