Windows Collaboration

"Windows Collaboration is a P2P collaboration application that allows people with Windows Vista systems to work remotely together as if they were in the same room. The application lets you share desktop with other coworkers, distribute and edit documents, send IMs and pass notes around. Users can also play multi-player games easily using Windows Collaboration. This application will work with existing wireless or wired networks if they exist, but if no networks are found, it sets up a special ad hoc network with other nearby participants using Wi-Fi technology. In this way, Windows Collaboration is different from other similar P2P applications or an actual Internet connection if the participants are all nearby."
