To the resolvers, all servers are peers.  The resolver will resolve
from any one of the "peer servers".  It does not differentiate among
them.

When you maintain name servers, you are certainly welcome to designate
several of them masters for the same zone.  There is no standard,
however, for how you would then keep them synchronized.  You would have
to keep them synchronized yourself.  The current standards for
synchronizing slave servers with master servers surely seem simpler
than that.

Exactly so, which is why the concept of multiple masters doesn't seem
very reasonable.
