The potential integration of video chat in facebook using skype technology in the backend is an interesting proposition. If you are ever to use such a thing, would you like to telecast your video one-to-one or would you like to broadcast to your contacts? Today, the voice based chats using skype are usually one-to-selected-group. One may end up with a similar notion on facebook too. This is very different from text based chating with many at once, using time based multiplexing.
