Should I consider using Iroh for intranet communucation ? Is it a viable use-cases? The use-cases I have in mind is an app being deployed on a HPC cluster, onto many nodes, cut off from the internet.

I had been looking at zeromq, but I very much agree with using keys rather than IPs where possible (after years of using yggdrasil, wireguard, tailscale, tor), so I am tempted to try Iroh. OTOH, this seems overkill if I'm using a client-server approach where the server IP is known.
