flash doc,pdf,txt,etc viewer needed

need a document viewer similar to [login to view URL]'s and [login to view URL]'s - doesn't have to be as fancy as theirs, however it needs to be flash, embed into a site and pull the file it's viewing through a querystring or XML. (example: [login to view URL] would display /files/[login to view URL] in the doc viewer) - needs to work with at least doc, pdf, txt, xls (more text extensions preferred) should be able to full screen, enter page # in a textbox, next/previous page buttons, and an embed link (should be embeddable on anyone's site via the embed code provided by viewer to user)
