Ingenious! An enhancement of this technique could be used on one’s own private network of DNS resolvers for the specific purpose of acting like a highly available directory of private cloud nodes, storing the following information: host:service:port:protocol encoded in one DNS TXT record per service. This would kind of be like a mashup of Apple Bonjour and this technique. The big question is, how long to cache the information for in such a setup, assuming the cloud itself is highly unreliable, so as to make the entire thing extremely fault tolerant?
