Could you build this?
Partial The browser front-end is straightforward, but establishing peer-to-peer or relayed connectivity to arbitrary machines behind NATs without credentials requires robust WebRTC/STUN/TURN signaling or reverse-proxy tunneling infra.
What it would actually take: The system requires an agent running on the target machine (written in Go or Rust) and a browser interface using WebRTC DataChannels or WebSockets, bridged via a public signaling server (and TURN relay fallback for symmetric NATs). The major engineering hurdle is resilient NAT traversal (ICE/STUN/TURN) and secure authenticated handshake protocols over untrusted networks. This requires networking infrastructure engineering and deep protocol understanding.
