High bandwidth connectivity in developing countries?

Assistant Professor Vivek Pai and his research team at Princeton University have developed HashCache, a highly efficient method of storing frequently accessed Web content on a local hard drive instead of using precious bandwidth to retrieve the same information repeatedly. This reduces the cost of networking, and enables small computers such as those used for the One Laptop Per Child project to access high bandwidth content. It also enables classes of students who are likely to be accessing the same content to do this cheaply and quickly.

In this video, Vivek Pai talks about the new technologies that could help make Internet access available to people in remote areas, especially in the developing world — where network access may be available only intermittently or with low reliability.
