One shot conversion is nice; but a web application that does it continuously will be much more useful. The beauty of an RSS feed is that you will get the updates.
I create cronjobs which run ratt regularly and save the xml to a file in a directory to be served as file by a web server.
After that i can just subscribe to it with my feedreader.
Maybe i will try to use it as a building block for a webservice, but for now i am still figuring out how to write good config files.
