The Downhill Battle people are hosting a web-based script that searches the iTunes Music Store and allows you to interact with it as though you were using a copy of iTunes itself. The script is open-source, and they hope the script will be used for innovative functionality in other apps, like providing 30-second previews and metadate for tracks on P2P nets.

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
