I imagined a situation in which you don't trust your resolver, even in 
same LAN. Due to ARP poisoning,  DNS request (even your local resolver 
issues external requests) can be spoofed and incorrect data can be returned.

I think using bind locally as a resolved indeed eliminates this issue, 
but with DNS caching in place I fail to see the reason of using a local 
DNS resolver, instead one can use a network resolver. Just a little more 
flexibility.
