You define the "master" nameserver as a supermaster in your pdns slave
(you don't want to be slave for the entire world, do you?).
If you add a domain on your master dns-server (any dnsserver that sends
bind-style NOTIFY messages will do), and define your slave ns as one of
the NS records for that domain/zone, your master dns-server will send a
NOTIFY to the slave. At that point, the pdns-slave receives the notify,
notices that it has no info on that domain, but recognises the master-ns
as a "supermaster". It will then automagicly add the domain, perform an
AXFR from the master etc...
This basicly solves the old problem of finding a way to notify slave
dns-servers that a new domain has been added on the master dns server
