Abstract
A screen sharing presentation system includes a presenter client system that leads a presentation and listener client systems that follow the presentation. A server facilitates communication between the presenter client system and the listener client systems. Users of the client systems may provide annotation information for the presentation. The annotation data is not visible to other users of other client systems, but is displayed on the respective user's personal views of the presentation. The presenter client system and the listener client systems are synchronized by communicating a current document location or other status indications.
