Abstract: A system and methodology for collaborating. The system is comprised of a plurality of computing appliances, each of the computing appliances having an input apparatus providing for a respective user input of and storage of annotations input relative to and while viewing a display presentation of a specific image and each of the computing appliances having a display apparatus providing a display presentation of a specific image to be viewed by an associated respective user of the plurality of users. Logic controls communication and utilization of selected annotations in providing a display presentation. At least two of the plurality of computing appliances have input apparatus each providing annotation data responsive to the associated respective user input of annotations using the input apparatus. Memory provides associative storage of the annotation data as mapped relative to the associated respective user of the respective computing appliance providing the respective user input.

Abstract: A system and methodology for collaboration and display among a plurality of users. The system is comprised of mapping logic defining a mapped structure for storing a plurality of separate layers of data in a plurality of data layers; and, storage for storing layer data in selected ones of said plurality of separate data layers, responsive to the mapping logic. The mapping logic associates user image data for each of at least two of the plurality of users for storage as respective said layer data in a respective one of the separate data layers. The system is further comprised of display definition logic controlling which of the plurality of data layers are utilized in providing a display presentation to at least one of the plurality of users.
