I am a perpetual traveler and I cannot bring a raspberry pi with me all the time and connect it to every hotel and airbnb.

I also do not trust the security I would be able to achieve on a VPS.

I use lightning for bitrefill, not only for zapping, so I cannot just keep 50k sats on a VPS and the problem is solved.

But I am very eager to read some solutions that other nostriches implemented.
