I used Tailscale on my remarkable tablet for a while; synchronizing documents over ssh is a lot easier with a static IP. It's fairly hard to get stuff to start on boot on the RM, or at least it was at the time, so I eventually moved off that plan. But it was pretty awesome to be able to ssh in from anywhere in the world.
Rmapi calls to sync. My use case is updating an annual calendar pdf which is inked on tablet but shows calendar updates day to day, so I run it on a cron
