Partial Basic LAN file, text, and emoji sharing is vibe-codeable, but the zero-config virtual LAN implied by the name needs NAT traversal, encrypted tunnelling, and peer discovery across networks, which are hard networking problems.
What it would actually take: A LAN-only version could use WebRTC or a local WebSocket server with mDNS discovery, which is achievable with AI assistance. A true virtual LAN needs a userspace tunnel such as WireGuard-style crypto, a STUN/TURN and relay infrastructure for NAT traversal, and cross-platform networking expertise.
