There is always the option for gorilla node deployment. They need very little power, so solar etc is an option, and the hardware is relatively cheap.

A cheap drone could easily place nodes in hard to reach locations e.g. top of telephone poles. You now have an anonymous node that is trivial to connect to but harder to disable.

It's far from perfect, but a good option.

I also now have the image of a node built into a drone. Then it bolting, like a startled sparrow, when they try to remove it...
