Enhancing ProBIND to support BIND-SDB master servers while keeping traditional configuration files for the slaves looks feasible. Would there be interest in the BIND community for a version of ProBIND with SDB support, or am I re-inventing the wheel? There are a lot of dead and outdated links for BIND-SDB. Is it viable for long-term use?
