iTunes Podcast Subscription Without iTunes

I've successfully ditched iTunes for managing my iPod thanks to Winamp and the ml_ipod plugin, but there was one nagging foolishness left; how to subscribe to a podcast that only sported an iTunes subscription link?

My friends, all you need do to cast off the last iTunes chain is install Greasemonkey and then (after restarting Firefox) install this GM script. This loverly script catches the itms URL and parses out the base url, which it then displays in your browser. You can then just copy that URL from your location bar and feed it to Winamp.
