Method, software, and system for efficiently enabling n-way collaborative work using common software over a network of computers. In a preferred embodiment of the invention, each participant in a collaborative session starts up a common software application, which includes a collaboration component. This collaboration component is used to establish a common session that includes all interested parties. The collaboration component replicates operations performed on any one instance of said application to all other instances participating in the same session, so the effect is as if all members of the session were sharing a single instance of the application on a single computer. In one aspect, the collaboration component also supports broadcast of audio and video over a computer network, to enable session participants to see and/or hear each other, and further includes other features that support collaborative work.
