I know this might sound odd, but ETCD and DNS look pretty similar. They are both hierarchical distributed key:value databases (well if you ignore SRV and TXT records...) Both have a system for time limiting keys. However etcd comes with a REST protocol built in, and higher latency. I'm not saying that DNS is better than ETCD.
