as long as you have a MP3 player (like Windows Media Player or Jukebox, for example) you're in business to PLAY them. And a lot of the shows have made them RSS friendly so that you could download them at night and look at them the next day if they're really large files.
What's exciting to me about this is the non-radio part of this, but using the internet instead. Right now big business has a majority of lock on radio stations and can set the bar about what they play, how many commercials, etc. If you want to set up your own radio station, it's expensive. Imagine, instead, that on your computer, you create your own radio program and then list it out through one of the podcast directories (like this
http://audio.weblogs.com/ ) so that other people can find it. You could do whatever you want, anyone can go get it and watch it (assuming they find it, for example). You could make your own list of shows you want to listen to every day and download them (to your Ipod or your computer)and thus be FREE to listen to what you want and how you want.
Here's an example of two guys who have made their own show.

This whole thing is like, instead of being led into a restaurant where your choices are baloney sandwiches and coke, you are at a smorgasboard table groaning with food choices.
