In addition to what the others wrote (a local Matrix server and UnifiedPush provider such as ntfy would work fine), I suggest you look into p2p messaging systems such as Briar. I think Tox is also p2p?
Lastly, Secure Scuttlebutt was actually designed on a boat for sporadic internet connection and local connections, as well as sneakernet, so that would work too, but I don't think it's designed for IM. Perfect for blogs or facebook-like stuff though.
Have a member of the crew go onshore up to a Wi-Fi AP, it will act as an async data transfer for everyone. You can also exhange data with other travellers, including passing boats.
Interestingly, there are a few Matrix p2p experiments. I wish apple opened their Airdrop feature as that would make proximity networking easier, though that should be achievable with Wi-Fi NAN+P2P.
- Arathorn 4y agoAirdrop (AWDL) is open, within iOS and macOS at least, and P2P Matrix uses it :)
- MayeulC 4y agoAh, thanks for the correct term. I am not sure the specification is open enough for other operating systems to support it, which is what I meant. Among my acquaintances, I can count Apple users on a single hand (<1% of the people I know), which severly limits the usefulness of the network. There's OWL [1] which looks promising on Linux. I hope Android devices can get something soon. I'm still a bit confused by how Linux drives Wi-Fi radio, and what is and isn't implementable in software: could older Android devices gain support for NAN and OWL through a software update? What about old computers with old Wi-Fi cards? I first got aware of Wi-Fi NAN by chatting with neilalexander on #yggdrasil:matrix.org :) It looks promising for advertising capabilities to nearby hosts, allowing to negotiate p2p connections.
