I think the extra code will mostly just get in the way of someone trying to grok the JS, especially non-JS devs. I would prefer to see this as a blog post/tutorial/article on AeroGear.org instead as the info is very valuable I just think it needs to be outside of the actual quickstart.

Indeed, a blog post on weinre would be rad - wanna give it a run sebi?
