I hadn't even heard of the underlying protocol NNCP yet, and it seems to solve out of the box several things I was trying to do in some of my own hobby-projects. I'd been battling with automating and integrating Tor/I2P, Openssl, Tox, GPG, Wireguard, etc. If NNCP lives up to the hype it will be a big shortcut, when I next get time to work on stuff :-)
I wonder how hard and if feasible at all it would be to have something like an email over NNCP over meshtastic network. Total independence and resilience.
I remember as a kid I set up one of the first private Echomail nodes as part of my RBBS bulletin board. UUCP was a big part of that, as I was the hop for other nodes coming onboard in my area. I added another half-dozen modems eventually just to handle the email traffic, then had to offload it to a university because I didn't want to have to charge for the traffic and it was getting too big to handle. But it was pretty interesting at the time.
