We introduce the concept of semantic multicast to implement a large-scale shared interaction infrastructure providing mechanisms for collecting, indexing, and disseminating the information produced in collaborative sessions. This infrastructure captures the interactions between users as video, text, audio, and other data streams and promotes a philosophy of ltering, archiving, and correlating collaborative sessions in user and context sensitive groupings. The semantic multicast service e

This contextual focus is accomplished by i n troducing proxy servers to gather, annotate, and lter the streams appropriate for speci c interest groups. Users are subscribed to appropriate proxies, based on their pro les, and the collaborative session becomes a m ulti-level multicast of data from sources through proxies and to user interest groups.
