Sound channel app

Hi!
Is there an application with which you can send some audio to headphones jack and some to built-in speakers?
For instance:
I have external speakers plugged in and I want only iTunes to be heard there, all other sounds (system, Adium alerts, etc.) I want on built-in MBP speakers.

I think Audio Hijack Pro (I think it's called that) does this kind of thing. Give that a try.

For anyone who is interested...
It is a hardware 'feature', you can not use both output devices at the same time...
