XCast is a project to build a controllable, mobile, personalized broadcast system in an infrastructure-free milieu. It has two goals: to permit people to create instant multimedia broadcast "stations" for extemporaneous events or individually motivated presentations, and to explore the ways by which such trust-based networks can be made robust in the face of external disruptions such as spam and overloading. This project is targeted at interactive, participatory broadcasting applications where each member are fluidly and easily a consumer and producer of information to which others can contribute and explore. There are two challenges: making limited radio resources more scalable over open and existing wireless networks without any mayhem and making it an attractive application.
