Can I build a new DNS/BIND system parallel to our existing DNS production system?

Hi Samad,

It's entirely possible to roll out a parallel BIND installation.  We're 
doing something similar at Brandeis right now--a mix of BIND and 
PowerDNS servers.  I take it that your current BIND setup is purely 
authoritative?  Or is it also handling recursive requests?
