This paper describes the origin and work of an independent research and development facility whose role is to catalyse the development of broadband applications for education. The paper describes how a three pronged approach is helping content developers understand the opportunities and make use of good research and practice in learning to develop the kinds of application that make use of emergent technologies, creative skills of the media industry and of educational thinkers, practitioners and researchers. Media streaming in itself does not make a contribution to education, and owners and developers of such technology need to develop a dialogue with other actors. This paper describes one such actor that works to catalyse and mediate between the many actors that are needed to make successful experiences and provides two concrete examples of activities that are providing a demand for streaming.
