webRTC is a disruptive communications framework open-sourced by google a few years ago.  It allows browser to browser peer communications.  It supports three channels, data, video, and audio.   Currently, Chrome, FireFox, and Opera are the only browsers natively supporting webRTC.  Internet Explorer, Safari, and IOS can be supported using third party add-ons (extensions).  webRTC is significant in that it allows developers to focus on UI issues and customized business processes rather than having to address complex communications issues.  webRTC is becoming the dominant technology used to develop applications for healthcare and enterprise customer support.
