The only real problem I foresee with this use(fantastic use case btw) is if you travel across regions, does the kit currently get automatically switched to correct frequencies and power limits?
The trickier part is to figure out the correct preset for more exotic locations. I've had to ask a couple of times from the local Meshtastic community group.
So to refine the gp's question: surely there's a way to push an update or sync with a script that can do this based on GPS coordinates, right?
I would think a syncing mechanism would be a big help anyways since regardless of the reliability of the GPS script you're still going to be doing this, right?
Though bigger reason likely is that very few people actually travel between different regions
