Interaction will skyrocket the pricInteraction will skyrocket the pricing, make it non maintanence free and requirethe user to have complex equipment rather than plain old fm radio. You are talking of thousands of such devices, so capital costs must be low and maintanence must be ZERO. For infrastructure like roads governments are unable to provide a modicum of maintanence. For something as "superflous" as this it would be dead from day one. eg train anouncement system costed 4.5cr and plays half sine wave - would give a rock band the shakes. > if we actually follow the idea of identifying the person and > sending proper signel then it will be much better. U are jacking up the price by orders of magnitude. While the tech to do all sorts of gymnastics is easily available, maintainig and keeping costs down would be impossible with anything but the sipmplest system -eg coupon stamping machine with fancy printer and stupid electronics now replaced with sophisticated fully interactive rubber stamp. I really fell on the floor the first time i saw that. -- Rgds JTD -- http://mm.glug-bom.org/mailman/listinfo/linuxers
