Darren - except for the NS records itself, everything you want to do works
as you describe above. The only time when you hit a "problem" would be when
you truly change nameservers or nameserver IP addresses.

Additionaly, as of this afternoon (see my earlier message), PowerDNS can be
made to emulate what BIND does exactly.

I'll explain in more detail later, am busy now. 

Good luck!
