To the extent that I understand what you're trying to accomplish, the
safest solution is to use a separate master server with reliable
connectivity to both locations, and have the authoritative servers at
the locations slave the zone from it.
If you cannot guarantee reliable connectivity then the alternate
solution would be to have each location dynamically update a subzone,
and then they slave from each other. I don't understand your reasons why
you think that's not an option, but if you can expand on your concerns
perhaps we can address them.
