Google hangouts are video chats with up to 15 participants who also have Google accounts. Along with sharing video from your webcam, you can also share your screen (helpful for giving presentations or demonstrations), collaborate on a Google Doc, or watch a YouTube video together.
The video quality is not as good as some other CIS-supported conferencing services, but it is fairly easy to use and requires little setup. One benefit is the integration with other Google services, such as calendar events and documents.
