We do something like that.  The implementation is something like that 
described in http://blog.eukhost.com/webhosting/simple-dns-cluster/

We use rsync to pull named.conf from the primary to the secondary, run a 
script to pull out the domain names and create a file that is then 
included into the secondary's named.conf.  We then do an "rndc reload" 
to get bind to use the updated file.
