Internet radio

So I wanted audio for my Gumstix Verdex, but I've already used the expansion ports for other cards. So I got a USB sound "card", a Hercules Muse Pocket LT. It works out of the box with the snd-usb-audio kernel module, and I can now listen to internet radio with eg:

wget -O - http://some-mp3-stream-url | ./madplay -
