I have some experimental "autoslaving" code which automatically creates 
zones on a slave server upon receipt of a signed-and-verified NOTIFY 
from a designated master server. However, the code has problems -- it 
doesn't run at all in multithreaded mode, for example. I'm not 
comfortable releasing it.

In the absence of something like that, you could perhaps periodically 
scp or rsync-over-ssh an "include" file consisting of slave-zone 
definitions.
