I was wondering how the services like http://www.inspectlet.com/ does store the video sessions. By the looks I don't think it's a webRTC implementation. What i was able to figure out that there is active express socket which is making communication but in that case they will have to store the page and track all the events from DOM. Just wanted to confirm that this is the approach they are following.
Looking at the event listeners on the page, it looks like there are a lot of bindings. For example, the <body> has scroll, keyup, and change events bound to a function. I'm sure it also has mousemove, mouseclick, etc. All of this is likely stored in a Javascript variable (object, probably) and then AJAXed every so often to http://hn.inspectlet.com/adddata with the data parameters. Here is a sample of what is being sent:
