A multimedia collaboration system and method utilizing an unshielded twisted pair (UTP) network among a plurality of workstations, the UTP network defining a data path along which data can be shared among workstation participants and an AV path along which AV signals, representing video images and spoken audio of the participants, can be carried among the workstations. The system is configured to manage a data conference during which the data is shared and interactively displayed on at least two participants' workstation monitors, and to control the reproduction of the video images and spoken audio of one or more participants at the workstation of another participant during a videoconference.
