I don't know much about VST, so I may be not understanding your point.
If "offline" means non-real time usage, AU can still be used "as is".
Instead of connecting your graph to an OutputAudioUnit, just call
AudioUnitRender on your graph root AU (you can use your own buffer size
there) and the audio will be rendered by the graph at your own "speed".
You get the audio buffer when the call to AudioUnitRender returns and
do there whatever you need with it.
Which begs the question: are there any plans for an Offline mode for
CA plugins, in the manner of the VST Offline API? I am very interested
in developing a host for Offline plugins, which would be at last some
mild competition for WaveLab; but as I am underwhelmed by the present
atate of VST, it would be good to have an AU option too. Offline
processing remains an important task, which should not be forgotten in
all the excitement over real-time stuff.

Realtime plugins (AU or VST) don't have any concept of the audio
files being used (if any). They only see audio input samples
(perhaps) and then send out their audio output samples. That's it.
If you need to directly handle the audio file data coming out of your
effect or instrument, you need your own app.
