I tend to use Bind for DNS stuff, it's quite flexible, in these

Either reduce the number of machines with master zones, and then
replicate would be my initial approach.
(Assuming i understand the above parag, of yours, correctly)
your WEB server --> web.example.org # 1ry for several domains
your APP server --> app.example.org # 1ry for domain + subs
another box --> ns7.example.org # becomes secondary
# (nothing special about 7)
so, add web.example.org to act as a slave for app.example.org (remember
to allow transfers from/to)
and allow domain xfers to ns7.example.org from web.example.org,
and set ns7 as a slave for all of the domains.
Then update the domains' NSes, and hope nothing's broken :) --- allow
time for DNS to propagate and as, ever, reduce your TTLs before you
start -- to speed up transfers/speedily repropagate fixes to cock-ups.
Presumably, you'll want to sort out rDNS too.
