My friend asked me to do a quick search for wireless cafe's in Danang where she's staying for the Tet holidays. Wireless cafes are spotted throughout Ho Chi Minh City but do they exist in Danang, or for that matter, in some remote area of Nepal? Eyebeam Re:blog has an interesting post on this subject.

In almost every village, town, or city in the developing world, there are people who can build just about anything. With the right know-how, this can include wireless networks that connect their community to the Internet. The book addresses what Rob Flickenger, the book's editor and lead author, calls a chicken-and-egg problem: "While much information about building wireless networks can be found on-line, that presents a problem for people in areas with little or no connectivity", said Flickenger from his workshop in Seattle.

In the developing world, one book can often be a library, and to a techie this book may well be a bible. Access to books is difficult where there are few libraries or book stores, and there is often little money to pay for them. "Our book will be released under a Creative Commons license, so everybody can copy and distribute it free of charge. That doesn't mean it is a 'cheap' book. I think it is a great book," stated Corinna 'Elektra' Aichele, one of the books co-authors who was recently installing wireless networks in Bangladesh.
