thejrwr writes to mention a CNN article about the ballpark stadium of the future. The new Cisco stadium for the Oakland A's will be a paragon of the company's technologies, with cellphones carrying personal data used for advertising and identification purposes. "Cisco, which makes the routers, switches and other devices used to link networks and direct traffic on the Internet, is trying to shed its image as solely a maker of networking infrastructure gear. The company also hopes to capitalize on products and services that utilize the network. One example is TelePresence, a technology similar to video conferencing that Cisco introduced last month that aims to deliver a three-dimensional feeling that the participants are all in the same room."
