If you want jack-support for a juce program, you can
copy code from Mammut.

In the src directory in mammut there is a file called
jackplay.c, which provides a
function called init_jack. init_jack takes a function
with similar API to juce's "audioDeviceIOCallback"
method. This should make it quite easy to dispatch during
init whether you want to play using juce or jack.
