I want to create an AudioUnit that has access to all the data in

Is writing an 'auol' AU a good approach? Does Logic or any other
DAW support these plugins?
You cannot have access to all of the data in one track unless you
write a DAW. It's still the responsibility of the host application
to manually feed all the data from one track into an AU, and then
capture the output elsewhere, if that's what you want. 'auol' simply
allows the host to know that an AU can be used in non-real-time mode,
potentially bouncing a track to disk in less time than it would take
to play, but sometimes taking longer than real time. CoreAudio is
always a pull model, so the speed and data flow are always controlled
by the host.
But you are right about one thing: If you find a host which has the
features you want - processing an entire track through an effects
chain and writing the new data to a new track - then an 'auol' is the
right way for you to implement the processing you want, provided you
understand that the reading and writing of data will be handled by
the AU host.
