  No, you can not:

/apple_ref/doc/uid/TP30001182-BAJBHIDI

  Not everything is observable because not everything is compliant. 
There are a number of reasons why it might not be feasible or why it 
might be woefully inefficient to use KVO.

  I take it, Chris, you really like the KVO mechanism. I do to. ;-) 
But you can't fit everything into it, nor should you where performance 
is more important than programmer convenience.
