1.  Thanks for the awesome explanations.  I've been dealing with these 
terms for a while, but had not really grasped them too hard until now.  
(To be honest, I had not looked them up in a while either.)

2.  When would a directed broadcast be useful?  Not only for WOL, but 
for some disk imaging software (e.g. Symantec Ghost), directed 
broadcasts is a way of pushing an image to multiple clients 
simultaneously.  Ghost specifically offers the choice of multicast, 
directed broadcast, and unicast delpoyment via radio buttons on the 
options page before a "ghostcasting" session is started.
