The data server (10) retrieves at least one data object (16) from among a plurality of data objects (16) from the data server (10). The co-presence server (20) includes a virtual place generator which generates one virtual place (24) per data object retrieved from the data server (10) and an associator which associates each virtual place (24) with its data object (16) once its data object is accessed. The downloadable co-presence client (48) is operative with the data retrieval client (12) and communicates with the co-presence server (20). Each co-presence client (48) includes an object associator which associates a data object (16) received from the co-presence server (20) with one of the at least one virtual places (24) in the co-presence server (20).</p> |
