Yeah, workshop is a verb now, at least applied to writing. I do a lot of it at three different forums (resulting recently in a collaborative novel project - I had vowed to avoid the pitfall of attempting a novel, but... ~sigh~), and I'm in that mode at the moment.

Anyway - points to consider in the scenario:

Basic literacy may depress the learning curve for a while, depending on the target 'market'. O.t.o.h., there's usually at least one person in a village who can read who isn't also aligned with the oppressors running the place.

Tech detail: don't forget the wind-up dynamo power source option. Not all of those "nasty" countries have optimal weather for solar, and photovoltaic panels would be noticeable from the air. If some of it turned into a genuine insurrection, they'd be hiding the hardware (cf. WWII-era Resistance cells).
