This was a problem in Mexico in 2006, too. There were also questions of infrastructure, since many schools were located in places that had no telephones or internet -- some even lacked electricity or as much as walls (palapas). The solution we came up with while working on a contract for the Secretariat of Education was to cobble together telephone, DSL, cable, microwave cell towers, and even satellite bandwidth to connect all the schools in MX in a virtual private network for the transmission of an interactive educational suite named Encyclomedia.
Besides sending a crew to install the equipment along with whatever specific safeguards it might need (power, ground, enclosure, etc), they would also walk teachers through the use of the rig, in particular the VoIP phone, which was connected to a central help desk in Mexico City by means of a "panic button." We also had regional IT guys who could get out to any school in a few hours to do maintenance work.
Now, yeah, this was a Federal project, but the point is that most problems are resolvable and -- just 4 years later -- at a much lesser cost. People intimidated by computers need only be told how to turn on a laptop in order to be walked through basic functions with automated software tutorials. As for infrastructure, that's just not a problem in this country.
