Plazza brings group formation and dynamic content distribution capabilities to broadband wireless devices, together with the illusion of infinite bandwidth and storage. Formerly restricted to PDA functionality, these devices dynamically discover content available in the wireless local network and other user's access patterns to it. Users can discover like-minded individuals or leverage implicit collaborative filtering to select the content they may be interested in, share the content with other stationary or mobile nodes, and view it in their devices or arrange for it to be transferred to their home node, where they can enjoy without battery or screen size constraints.
