Dane Stuckel, Carl Gutwin. The effects of local lag on tightly-coupled interaction in distributed groupware' CSCW 2008.
Comments: Local lag here means forcing delay on users' actions so that it matches the group (for distributed group work delay due to bandwidth). Users were better able to manage a sluggish system than remote delay. Also, an echo effect (where users can see both their immediate actions and the actions as they appear to the group) just adds confusion. Cite this for justification for local lag setup with Cocomo. Also, some nice terminology feedback and feedthrough different between immediate local effects of actions and delayed group effects of one's actions.

Comments: Compared a 2D and 3D interface for conferencing video windows. Participants could configure, place, and zoom windows. Knowing who is speaking in a meeting is important. Automatically rearranging windows to signify importance is disorienting. 2D did better for seeing participant's faces. 3D is better for knowing where participants are looking. 3D not important for seeing transitions.

Comments: Automatic capture of lectures. May be less relevant as its focused on stage performance and motion-tracking cameras.
