It can be just like you’ve said. You can also run tailscale directly on the system hosting a service and access it directly over the tailscale network.

Just use Snapraid & MergerFS. No special Hardware required and you don’t need to change what is on your disks.

From a quick search: https://perfectmediaserver.com/02-tech-stack/snapraid/

This is how I do it. No striping, normal partitions, different hard drive sizes, pretty easy. This way makes upgrades super easy too. Currently running 76TB mergerfs with 2 14TB Snapraid parity drives.

I know that Pixel 7’s and above support it. There are Reddit posts showing they have the feature already. Satellite messaging is just using standard 4G/LTE from Starlink. I wouldn’t be surprised if this is only an OS update away for most newer phones.

Looks like it’s been available on some android devices for at least a month. I don’t know about free though, I think it depends on your carrier. I know T-Mobile has been talking about supporting it using Starlink satellites.

This is the best answer I’ve seen in this whole thread. You’re right that the key is not needed. Microsoft identified your system components and did the original activation based on the hardware you’ve got on your computer. All you need to do to bring back a licensed copy of Windows is to reinstall it.

I get alerts on my Android for an Airtag I keep in my backpack all the time. My phone gives me the option to make the Airtag play a sound.

On Debian, you have to be root or a sudoer. Those commands are there, just not in the path of regular users.
