but only if you violate some pretend privacy rule and look at what in  
context is actually just data. What element of a given nodes  
functional role, in a layer context, demanded it have consciousness of  
the payload to perform its role?

I can't help feeling that there is a chinese-room or black-box view on  
this that says if you don't NEED to look at whats in a bit string to  
perform your functional role, then if you do, you are possibly  
exhibiting side effects..
