Low Tech Gutenberg?

Peace Corps Guy asks: "I have a friend who recently left for a two year Peace Corps stint in Mozambique. While there she has limited access to electricity, no technology, and not a lot to do with her 'off' time. She's a big literature fan, and many of us here at home would like to send a care package - but how best to ship pieces of free online text like Project Gutenberg to a developing nation? We can print it (high shipping and printing costs), print it very small and ship her a high quality fresnel lens (awkward), or put it all on a cheap PDA, which would be a high theft risk en route and in situ. High shipping costs on weight and volume are another major limiting factor. What alternative solutions can Slashdot readers suggest for shipping a freely available byte-stream to someone without a computer?"
