well this is the same hoby project that i am working on. The thing is this is not remote control for "browser". This is remote control for the api integrated web page. Mine project called "peegle" works with a chrome extension. So I can call it remote controller for browser. Just check it maybe we can do something together.
You are right, for this demo the title is a bit misleading. Haven't really thought about it. However, my plan is also to create something similar to you at a later stage. To control one website with the remote, which will control the browser via a extension.
