—As a result of the wide spread of new efficient mobile communication devices, users are more and more willing to find on these devices (PDAs, Smartphones, etc) applications similar to the ones they are using on their desktop computers. We go one step in this direction and propose in this demo a software we have designed and implemented to enable content sharing among spontaneous communities of mobile users using wireless multihop connections.
