Remote Classroom In Developing countries

I read an article, where students in some parts of Africa has to walk 3 hours, just to get to classroom. (and that is on top of their other duties such as fetching water and etc.)

What if we can create a cheap simple rugged portable videoconferencing solution, that can be installed in a remote communities around the few schools in Africa(or any other countries with massive dispersed landmass, and a lack of transport facilities).

It will communicate to the main school via a unidirectional UHF antenna. (satellite is better, but more expensive)

What this means is instead of walking many km to their school, they can all walk to the nearest 'video conferencing classroom'. (which may consist of a tent and a projector/TV screen system.)

If possible, we can hitch this concept to the OLPC initiative, by making each videoconferencing classroom a wireless node for the OLPC laptops. (Thus increasing the mesh reach of the system)

Perhaps to pay for the system, we could also make each node, a cellphone tower as well. (On the condition that we can use part of the cellphone tower to exchange classroom videoconferencing data) Thus it become partially financially self sustaining.
