In this paper we describe a quantitative study of a group-to-group videoconferencing environment called GColl that provides a compromise between the need for preserving non-verbal cues and the requirements of low-cost and flexibility. We have compared the task process and outcome of participants interacting over an environment analogous to common commodity solutions, those using face-to-face communication, and groups communicating over GColl. Our results demonstrate that it is possible to design a group-to-group collaboration environment with modest technical requirements and low overall cost that still shows measurable advantages over the common environment in its ability to support trust in social dilemma games.
