Partial The desktop UI and features like chat, file transfer, and port forwarding can be assembled with existing libraries. Reliable peer-to-peer connectivity across NATs, with relay fallback and secure encryption, is a networking problem that needs specialist expertise to get right.
What it would actually take: Use an existing P2P or overlay library (such as libp2p, WebRTC, or WireGuard-based tooling) for NAT traversal, STUN/TURN relays, and encryption. Then build cross-platform desktop clients with a short-code pairing protocol and file and port tunneling. The hard parts are NAT hole punching reliability, security review, and running relay infrastructure at scale.
