Urs,
I think the idea is to avoid having the UI component talking to the AudioUnit
by directly calling internal C++ objects deep inside the AudioUnit. Instead
private/custom properties can be defined for the AudioUnit which the UI
component calls. Don't take this to mean that we're planning on having
components talking across different address spaces, etc. Remember,
that AudioUnitGet/SetProperty() deal with void* pointers anyway
so this wouldn't be possible.
Calling the C++ objects directly is simply not recommended by us --
that's all we're saying -- use property calls

I don't know, I think that some people started saying it, and then no one
ever said it was wrong. Despite Chris's post, I have been reading this
list for a long time (since before there were AUCarbonViews) and
definitely don't remember anyone every conclusively saying that this
wasn't the case, but perhaps that just slipped past me. So I'm not sure
how definitively to take Chris' comments, but of course we don't have a
definitive answer for either way.
Well, I've gone through all mails I have on my @work machine (it
lacks every Friday and Saturday), and couldn't find it. But I
definately remember this having been mentioned twice, something like
"direct referencing is highly dis-regarded".
However, Bill says something about using C callbacks instead of C++
object references here:

I'll probably find the correct mail when I'm home (or I'll have to
exchange the battery of my memory)...
Cheers,
;) Urs
