WebRTC makes it possible for anyone to create video and voice on the browser. But as cool as the new Web protocol is, it’s not always easy to work with. Building a full fledge video app requires complex and esoteric coding. You need other elements as well. For example, signaling to make the phone ring and authentication.
In the not too distant future unified communications will be a feature embedded in almost every new Web application, which from a developer perspective means that most end users are going to soon view most existing applications as nothing short of being antiquated.The W3C is currently working out the details of a WebRTC specification that essentially puts support for a real-time communication engine directly in the browser.
