This is a perfectly reasonable way to use NSD. In fact, it is somewhat
better than using zone transfers between one NSD master and some slaves,
because NSD is only able to provide a full AXFR, but not an incremental
IXFR. So rsyncing the zones is probably the most efficient. As a side
effect, you don't need to arrange for NOTIFY between the servers, nor
any kind of XFR ACLs or TSIG keys.
