Hello skipper,
I use Broadwave & ZaraRadio, it's easy to set up.
For ZaraRadio, just run it as normal, if you need help, send me a pm.
For Broadwave, you just need to set up the Live stream.
Broadwave Live stream takes it's input from the source selected in Windows "recording control". If you have Vista or Windows 7, I described how to do it here:

If you have XP, then go to record properties and select stereo mix or similar - the exact name will depend on your sound driver.
