So what you want to do is for _every_ lookup not already in your cache 
you'd want to do separate non-recursive lookups at each nameserver (try 
the "dig +trace example.com" command to see what I mean) instead of one 
recursive lookup?

Sure if you can find or write a resolver that'll ask the nameservers the 
right questions; it's got nothing to do with the DNS servers; they just 
supply (or fail to supply) the record they're asked for.

You can ask the question on bind-users but be prepared to be flamed.
