Thank you for sharing! This is one of the coolest articles I have seen in a while on HN. I did some searches and I think the search results looked very useful so far. I particularly loved about your article that most of the questions I had while reading got answered in a most structured way.

I still have questions:

* How long do you plan to keep the live demo up?

* Are you planning to make the source code public?

* How many hours in total did you invest into this "hobby project" in the two months you mentioned in your write-up?
