For this show I created a 4 way video chat system that ran over a wired or wireless network. The system used gstreamers h264 encoding and used a server/client architecture to aggregate all the feeds into a preview stream that allowed all the remote systems to monitor all the audio and video from other clients.
The audio feed was achieved using net receive and net send Au plugins coded inside the app using the coreaudio functions of OSX.
