SetProperty/GetProperty

In an effort to make sure my Views don't make any assumptions about running in the same address space as their AU, I'm looking to GetProperty/SetProperty to replace direct method calls.

Obviously in testing on current hosts, I can use the void* parameter in either call and treat it as an io param:

...

float32 MyView::SomeMethodProxy(uint32 inParam)
{
   struct someMethodParams params;
   params.p1 = inParam;
   params.retval = NO_VALUE;
   s = sizeof(params);
   AudioUnitGetProperty(mEditAudioUnit,
      kMyProperty_SomeMethodOnTheAU,
      kAudioUnitScope_Global,
      0,
      &params,
      &s);
   return param.retval;
}

...

since all the current hosts do run views in the same address space.

My question is whether we can reasonably expect this behavior to be reproduced by a host marshaling parameters across process/machine boundaries, or whether these void* parameters are intended to be one direction only.

Thanks,

Art
