Flex 2.0 and Local File System

With a flex 2.0 application is it possible to access local files without having to upload and then download the files??

I hav looked at this page: http://www.adobe.com/devnet/flash/articles/fplayer8_security_07.html  but I am still unsure of how the security works.

Is it possible for a user to "allow" or "trust" our application and grant it access to the local file system. If so, how then would I go about getting the full path of a file choosen using the FileReference class and load it into the flex app?

Please note that our application will always be running off of our server and will not be running locally.

Thanks
