Inline PDF viewer
Is there is PDF viewer which I can embed into my HTML and which I can style as I want.

Actually I need to show some page of PDF file and customize my own UI (few buttons to turn over the pages and commenting).

And if there is any Ruby solution (It's not actually about programming, as I understand) it will be great.

I want to show pdf because:

 - User can copy text
 - Text is in original layout

So I don't want to show it as images or as a converted text. But I want to show page in simple design. Without Flex or whatever.
