An interesting tool, developed by UBC which allows a group of people get together to watch a YouTube stream (ideally, a live stream, but it could be an Office rerun). In the sidebar is a video chat, so people can see each other reacting in real time to what they’re all watching. Sync is 100% free (no ads) and open source.
