I think the general consensus in the DNS field is that for security reasons it
is preferable to have as small a set of DNS servers (or perhaps as small as 
set of differently configured servers! Hmm physical security....) in the 
hierarchy above you as possible, since compromise of any of these could 
affect the results obtained for your domain.
