I just discovered that my TiVo knows about RSS feeds, and I can set it up to listen to podcasts (look under "Music, Photos, Products, and more" from the main menu, then find the Podcaster menu item). On the screen is the Camel with Headphones Perlcast logo, and I'm listening to Josh's interview with Steve Oualline. Very cool, especially since there's nothing on at 3 am.
Apparently I can also link to various Yahoo! services and a bunch of other internet stuff. Everyone else probably already knows this, though.
