The closest match to this in BIND currently is views.  If you've got  
fairly broad categories of IP addresses that you might give different  
answers to, and the addresses in each category are fairly fixed, then  
it would be pretty easy to set them up in views to present differing  
answers to each category.

Whether or not this will work depends on things like how many  
categories of source addresses you want, how easy it is to aggregate  
those addresses into CIDR statements (there's a limit on how long the  
match statement can be I think) and how often the categories will  
change.

HTH,
   Matt
