If I\'m not mistaken, Google Docs offers the means to display a PDF that is stored on the same server as the web page via an , but I need to know
If I'm not mistaken, the OP was asking (although later accepted a .js solution) whether Google's embedded PDF display server will display a PDF on his own website.

See http://googlesystem.blogspot.ca/2009/09/embeddable-google-document-viewer.html. Also, see https://docs.google.com/viewer, and plug in the URL of the file you want to display.
Edit: Re-reading, OP was asking for solutions that don't use iFrames. I don't think that's possible with Google's viewer.
