=> it is a DNS problem: if you don't try a multi-master setup with
a server software which does not explitely support it there should
be no issue: as I said dynamic updates are propagated between servers
(or they fail) so things with a sane setup can't go out of sync.

=> misunderstanding. Simply look at the DNS server documentation about
dynamic updates.
