If I remember correctly, proxies have indeed a bit of traversal magic 
that performs the (necessary) getContent.
I guess this is because we'd otherwise need to write a script for each 
method of the underlying object that has to be reachable through the 
web (cumbersome, bad for performance), although it's probably less used 
now than in early CPS3 days.

I agree that this blurs the lines between proxies and their content and 
surely doesn't help understanding them.
