—In recent years, peer-to-peer systems have gained traction in a number of important areas including; file-sharing, VoIP and scientific research vehicles such as the Grid. We argue that this merely scratches the surface of the potential of peer-topeer systems. This paper proposes a novel peer-to-peer system, GeoIGM, well suited to the highly collaborative style of tagging and development of context-aware services, particularly location. With the provision two fundamental operations; geographicallyscoped multicasting and queries, GeoIGM eases the development of next-generation location-aware systems.
