One comment I'll make because it's kind of buried in the first paragraph and not really called out: this project is one of the very early adopters of Trevor Perrin's state-of-the-art Noise protocol framework design https://noiseprotocol.org/ https://noiseprotocol.org/, so you're looking at something dramatically more modern, auditable and (potentially) secure than older, hairier protocols like IPsec, TLSv1.2, OpenVPN, etc. Best of luck, Jason!
