http://es.openoffice.org/?intcmp=1480 Is in the list this is the spanish site... A and yet a direct query of "openoffice.org" returns no direct link...

This may be an overly simple response, or it may not factor in you organizations security concerns which may or may not be unique. Why not just post the files some where and view them in a web browser, and disallow editing on the server end... Ie r--r--r-- permissions. I would imagine this would involve a very simple script to copy the files, and a very simple page to display a list of the files. Additionally I would make a note that a web browser can be launched from your executable as required.
