I'm interested in the same thing. I want to use this for a wordpress blog where the feed address is http://user.wordpress.com/feed/. Is it possible to do this without storing the xml file on the server?
Yes, I believe it will work. However, you may get a warning on your browser, depending on your security settings.
I recommend fetching the remote RSS file on your local server. This is pretty easy to do using php: http://ca.php.net/manual/en/ref.curl.php (example 417).
This application is working in IE perfectly but in mozilla nothing it is displaying for remote rss files.Is it possible to make workable in mozilla also for remote rss files.
