In lookng at other developing region projects I ran across the R.A.C.H.E.L. (Remote Area Community Hotspots for Education and Learning) project.

Essentially they distribute Raspberry PI cached webservers pre-loaded with education content so no need for Worldwide Web access to get content.

Mesh networks would be a great to extend the reach outside of libraries and classrooms to the community even in isolated regions with no WWW internet.
