Have a look at http://www.indexa.org/hamswithaheart.html
IINDEXA is proud to announce the formation of a new fund within INDEXA that specifically supports humanitarian projects carried out by DXpeditions. The generous initial contribution by Mr. Zorro Miyazawa, JH1AJT, will enable INDEXA to begin humanitarian support grants beginning mid-January of 2016. The tag line for this fund is “Hams with Hearts.”
It seems to me that ham radio would be an excellent method for extending the Outernet Community into the areas where the service is most used - many of your users on the ground will be technically proficient, and with the help of the Ham community, along with the possibility of a grant, is should be possible to get real two way communications going.
I specifically note the existence of a Raspberry Pi based TNC, and Digipeaters, for APRS, along with APRS internet gateways.
