Thanks all, for responding.

One followup question.  I am currently doing some engineering work for
GreatBigHugeCo, wherein getting things like DNS updates done is very
time and paperwork intensive.  Sometimes I think it would be easier
to do tensor analysis with an abacus, but I digress ...

For reasons too long and complex to explain, I may want to do the following
and need some input on how to implement this or whether it's even practical:

  - Run an instance of bind in user space so I can control all the 
    configuration without having root.

  - Forward all lookups not in my database to a "real" DNS server


What I am stuck on is this:  Is there any simple (i.e., non-root) way
to write a client or otherwise configure userspace to go to the non-standard
port and run my sort of man-in-the-middle server?  Or is this just a stupid
idea?
