This is the first time I’ve heard of Scuttlebutt. Thank you for the introduction.
For your multiple-device problem, I would suggest trying Syncthing. It allows you keep folders synced between devices over a local network. I use it for a very similar application to what you are describing:
Logsec is a journal/note-taking software that stores each entry as it’s own markdown file. I use it on my phone, laptop and desktop, and want to have all my notes synced between devices. I could put the folder of markdown files on a cloud server, but choose not to. Instead, I setup a link between each device’s Logsec folder through Syncthing.
Now I can add or update notes on my phone when out in public, and when I return home and reconnect to my WiFi it automatically updates the other devices on the network. Also, when editing the markdown files on my desktop, the updates are synced to my phone nearly instantaneously.
I expect this method would work very well with Scuttlebutt due to it’s similar offline nature.








Extended security updates are available. This can be activated for free using Microsoft Activation Scripts.
Microsoft tech support has been repeatedly caught using these scripts to resolve support tickets for license issues. (https://www.bleepingcomputer.com/news/security/microsoft-support-cracks-windows-for-customer-after-activation-fails/) Also, the open source MAS code is hosted on Microsoft-owned Github, so they are appearantly not very concerned with people taking advantage of this exploit.
If you go this route, please also see the FAQ entry here. There is currently a glitch with commercial ESU keys (which this uses) and Windows Update will continue to claim that your device will no longer receive security updates. This is also effecting W10 LTSC systems. However, you can verify that the license key is active through Command Prompt and instructions are given in the FAQ.
