Meetings by Skype often connect rooms full of people, each appearing as a tiny dot within the video from a wide-angle camera. It should be possible to use cross-correlation of signals from separated left and right microphones to identify who is currently speaking and automatically zoom the image to a specific region, enlarging the person who is currently talking to fill the screen. You should implement your solution as a replacement (software defined virtual) camera that outputs a modified video stream, to a standard conferencing application such as Ring for Linux.
