"Warchalking, as the practice has been coined by founder Matt Jones, entails simply drawing a chalk symbol on a wall or pavement to indicate the presence of a wireless networking node. If you see one of these symbols, you should--in theory at least--be able to whip out your notebook computer equipped with an 802.11 wireless networking card, and log on to the Net. The idea of organized wireless hot spots, where people can log on at cafes, exhibition centers, airports and the like, is nothing new."
