Podcasts in your car, easily?

That was what came to mind when I saw Damien's in-car computer at eTech. He's just started a Car Hacks blog. I hope he has a few posts planned on 'why is it so bloody hard to hook an iPod up to a car stereo, and what you can do about it'.
Shifting audio blogs from my computer — where I can't type and listen to speech at the same time — to my car or bike — where audio is a welcome enhancement — was exactly why I wrote the first RSS enclosures to iPod tool back in 2003, so I could listen to Chris Lydon's interviews while driving around. You can see me demo it at BloggerCon I (58 minutes in). Calling this idea podcasting came later.
Imagine it built into the car...
