I'm CCing ardour-dev so someone can correct any mistakes I make.  The 
topic is how to implement support for AudioUnit plugins (an Apple 
specification).

Ladspa plugins are run inside ardour's process callback.  Their GUIs are 
created and run within ardour's gui thread.

I don't know the details of how VST plugins are run through Wine.  It 
probably depends on the amount of seperation between the UI and the 
effect backend.
