Up to this point, we have covered a shallow portion of the entirety of WebRTC. This has been limited to what we could build in a chapter inside our local computer without hooking up to any real services. This is great if it's only limited to you or a few of your friends but, unfortunately, this will not lead you to being able to connect thousands of people across the world.
