I have no problem with this technology. It could open up many small rural communities not "worth" reaching by conventional systems, and for that I applaud it.
But even many developing countries have high population density, and a disorganized system running on a narrow frequency band will quickly run into problems of scale.
And the summary's grandiose claims that this technology could "do for mobile networks what TCP/IP and open source did for the Internet...help mobile break free from the confines of telephone providers' locked-down spectrum...democratize telecommunications around the world" are patently ridiculous.
To use the /.-approved Vaguely Relevant Car Analogy(tm):
A village in the West Papua central highlands has built their own road. Despite being made of smoothed dirt and barely wide enough for one vehicle, it meets the needs of the twenty-some villagers. Proponents of the technology claim these independent 'dirt roads' could help free transit from the grip of the heavily regulated national road networks, and may soon democratize travel around the world.
