nice work > I would not recommend anyone use this for anything other than entertainment. For what it's worth, we used a similar setup at a previous huge employer, but using powerdns with a custom backend adapter that hit a zookeeper cluster, serving a tiny subset of our DNS records (with really short TTLs so that changing ZK resulted in prompt DNS changes). We used this for Real Work, and it worked really well. So I think your approach is probably fine.
