ooVoo addressed the web, the desktop and mobiles as a video chat client coming from the future. It allows up to 12 simultaneously free video calls to your friends around the world, even if they are on different browser based chat services.
In order to start calling, all that is needed is a free account. Apart from group video in picture in picture view, this program also integrates a function that lets you watch the same video as your friends at the other end of the wire do.
Further uses can be found for this chat client, such as using chat rooms to speak to your community or to a certain group somehow related to your business. The video is in high resolution and it may be seen in full screen too.
