070 - Iroh

Iroh just hit 1.0, and it might be the P2P networking library I have been waiting for since college. Instead of dialing IP addresses, you dial cryptographic keys. Your connection survives leaving your Wi-Fi, switching to cellular, and moving across the planet.

I roughly walk through how it works, the Swift bindings for macOS and iOS, how they replaced TURN servers with a stateless relay you can self-host, and the protocols they have already built on top.
