This is a great article, if you look at webrtc support once Apple is out of the yellow zone with safari we have across the board support for webrtc in all browsers. Its still not a settled api so its pretty hair raising. My first webrtc startup failed but now I'm working on replacing a legacy flash system with webrtc, in this case with flash being phased out webrtc is the only choice. This article is really well done this is going to help me give something my cto can read and quickly understand so he fully "groks" what my team is doing.
