No worries. I had just spent a bunch of time replying to another guy about this, and then had to pop into surgery and recover for days, which is why I felt bad and specifically mentioned it.
Like I mentioned, this is inspired by an existing thing, so I know it's possible to not get caught if transmissions are kept very short, and done in a busy area. Definitely not recommending it, though; it's also just rude to fill up spectrum with massive cyphertexts if you don't have a good reason. Industry Canada (in my case) is one thing, but basic human decency comes first.
I hadn't actually thought of natural disasters. I suppose that could be a niche just because low-power transmitters are so much more common now. Above the physical layer it makes little difference as far as I can tell, so we can talk about that and not worry about the philosophy or practice of law-breaking.
So would the hub just function as a local network, then? I can see what you mean by that. So basically, each container would get an IPv6 address, and could communicate with the outside world normally when a low-latency connection - like maybe via satellite constellation - is up.
Hah, is there an official term for the move from one node to another? I'm pretty sure I've heard a complete mix of things IRL.
You could do full-blown onion encryption if you wanted, assuming you know in advance the path your traffic will take (or at least the very end of it). If you don't, you pretty much just have to trust everyone to see what route your traffic did take in the end. Given that nodes are mobile, can change identities, and optimally only share encrypted traffic, does that sound like a huge risk? (Honest question)
I suppose in a disaster situation, you could just openly publish the GPS coordinates of the hub, and make a transmission strategy by as-the-crow-flies distance.
I'm familiar as a user, but I'm not sure how few packets you could fit that into. You could definitely set your container to do a web of trust check over the normal internet, and just ask the other party to sign something with their published key.
Also, a bit off topic, has PGP/GPG already been adapted for post-quantum algorithms? You'd think it would be one of the first things to get set up.
