I wonder if Joey Hess has any advice he could offer to people in such a situation. He's obviously optimized how to be productive out in the middle of no where with limited network connectivity.

I reckon a big piece of being productive involves learning how to get as many needed resources available offline as possible. If you have offline resources, your biggest hurdle is limited to electricity availability, which I imagine can be solved with batteries and renewable energy.
