I saw this phenomenon in action this week while on a one-week expedition in the Panamanian jungle. Together with seven other international business executives, plus guides, and support staff on a trip organized by Earth Train, we hiked and kayaked the Cangandi River in the autonomous indigenous region called Guna Yala, traveling from the Pacific side of the continental divide all the way to the Atlantic ocean. What an amazing trip.
Even though I was "off the grid" for the vast majority of the time, I ran across people in some of the most remote parts of the world connecting to the Web.
In the village of Cangandi, with about 250 inhabitants, I saw dozens of people on mobile phones. This village has no running water (they drink from the river), they build their own houses from local wood, and they grow their own food. There is no electrical power, so they use solar panels to charge their mobile devices. They built the community on the top of a hill partly to take advantage of a distant cell phone tower.
If you are still clinging to the fiction that your buyers are not on the Web, you might want to ask if they own a toothbrush. I think you're living a myth.
