Mixer for JackOSX

Hi,

Are there any audio experts here? I'm trying to use JackOSX to mix and split multiple audio sources to send to a bunch of applications. Anyone know how to do this?

Specifically, I have audio sources from Safari, iTunes, QuickTime, iChat, etc. I want to mix these audio sources and output the result to the speaker. But I also want to take the audio sources from iTunes, QuickTime, and the Built-in Line-input, mix them and send it to iChat and the flash plugin in Safari. Is this possible? Any pointers are greatly appreciated. Thanks.
