Curious...  if a zone is updated (and the serial incremented <g>), and 
the master is reloaded, it *should* send a NOTIFY to the slave 
server(s), which will then AXFR the zone.  Logfiles from both sides 
would be interesting to see for the failure case.

I have a local RBL passed on to several local slaves this way;  the zone 
file is regenerated and BIND (master) reloaded about every twenty minutes.

The only case I can think of where this might not happen is if NOTIFY 
has been disabled - in an all-BIND DNS environment, I can't see any 
advantage to doing so.

This obviously doesn't apply to *adding* or *removing* zones;  so far as 
I know there's no way to do that automatically through BIND's own 
internal processing.  :/
