Podcast
Podcasting is a form of audio broadcasting on the Internet. The reason it became linked with the iPod in name was because people download podcasts (audio shows) to listen to on their iPods. However you don't have to listen to podcasts only on iPods; you can use your computer with some music software such as Windows built-in Media Player, Winamp, or other portable music players (iPod competitors) such as Creative Zen or iRiver. It really doesn't matter, as long as you have some way to play music on your computer you will be able to listen to podcasts.
Anyone can manually subscribe to the podcast by just entering the location http://feeds.feedburner.com/marshill/podcast into their respective podcasting tool (In iTunes it's under the Advanced menu "Subscribe to Podcast")
