1. A method, comprising, by a sharer network node: on a local display of the sharer network node, displaying a representation of a virtual area, a representation of a first viewscreen object in the virtual area, a representation of a second viewscreen object in the virtual area, a representation of a user who is present in the virtual area and operating the sharer network node, and a respective representation of each of one or more other communicants who are present in the virtual area and respectively operating one or more other network nodes; in a screen layout of windows on the local display, selecting multiple windows that are associated with a first software process based on user input in connection with the first viewscreen object, wherein at least one of the selected windows is at least partially obscured by one or more unselected ones of the windows in the screen layout; generating a first sequence of composite images of the selected windows as they are arranged in the screen layout at different respective times but free of obscuration in any area obscured by any of the unselected ones of the windows in the screen layout; transmitting the first sequence of composite images from the sharer network node to a particular one of the one or more other network nodes in connection with the first viewscreen object; and contemporaneously with the transmitting, communicating a second sequence of composite images of windows associated with a second software process between the sharer network node and the particular one of the one or more other network nodes in connection with the second viewscreen object.
