I don't disagree that root attacks to date have been largely  
ineffective, but "past results do not guarantee future performance."   
Given the vast numbers of botnets (both voluntary and involuntary),  
it isn't immediately clear to me that any centralized resource is not  
subject to overwhelming attack.  I believe the only real mitigation  
to this sort of stuff is decentralization.

For one thing, unless you want to play routing games and steal  
prefixes, it requires coordination with a root server operator.  An  
advantage to slaving the root is that you don't have to coordinate  
with anyone (assuming open zone transfer).
