Previously in using zerigo, the ttl for personatest.org was defaulted to 60. When we switch to route53, the above means it will be 600. Not sure if this really matters (i.e., how often do people destroy an awsbox instance and then immediately redeploy by the same name, but I know I have done so in the past on occasion, for reasons I don't recall). Anyways, 1) is there a way in route53 to allow a default for a domain, and awsbox just defers to that, unless 2) the TTL is surfaced as an option to the awsbox script, with a default for the option set to 60 seconds there.
