Well written. I did a very similar deep-dive Websockets presentation at a local JavaScript user group [1]. The presentation culminated in a live demo [2] I hosted on my laptop over the local wi-fi, allowing everyone in the audience connected to the wi-fi to connect with each other in the app. Of course, it only took the audience about 2 minutes to discover some cross-site scripting vulnerabilities in my not-meant-for-production demo app, which allowed them to start showing videos and playing embedded videos on each others' computers.
