Actually, the discussion isn't about the use of the DNS protocol  
itself as a botnet C&C channel (as you indicate, that's certainly  
doable), but rather about domains used as pointers to malware which  
is then distributed via various methods, same for phishing, as well  
as the use of DNS to provide server agility for botnet controllers  
irrespective of the actual protocol used for C&C.
