Lo-Techs
… not my style at all, but that was what I was aiming for: If they think you’re crude, go technical; if they think you’re technical, go crude. I’m a very technical boy. So I decided to get as crude as possible. These days, though, you have to be pretty technical before you can even aspire to crudeness. –William Gibson, Johnny Mnemonic
Sometimes, providing for the lowest common denominator means you have to get super innovative with your technology; witness the One Laptop Per Child project (which I have some doubts on the intended implementation, but the design at least is excellent) -- and sometimes, you just have get creative and get your hands dirty. For this, see the Blue Trunk Libraries for keeping doctors in remote areas up to date with medical advances, using a condensed "library" of books in a rugged, portable blue plastic trunk.
