You glorious bastard, what a cool project! This is already a contender for most hacker project of the year :-)

(below is not serious)

I would advise people against using this in production though because it's still missing some critical features. For example:

1. The Javascript stops working when printed to physical paper. The resulting paper just has a static image and the controls no longer work.

2. It doesn't work properly in Evince. It just shows an error "The document contains only empty pages"
