So long as I'm subclassing, I'd like to make the NSTableView
controller-aware for the purposes of: [...]
You could add an outlet to your table view subclass for the controller.
I know that requires one manual connection in IB, in contrast to
obtaining the observer/peer -- but in theory the content-binding might
not be to an NSArrayController.
[...] Unfortunately, apparently there is currently no public API for
getting a NSTableView's content binding.
I think (but I am not sure) that what happens when you bind something
together is that an instance of NSBinding (or similar) is created, this
object will observe both ends of the binding (i.e. the controller and
the table view), and if the value changes in one of these, it will set
it on the other object (if it does not already have that value).
So the connection from the table view to the controller goes through a
mediator.
