Comment:

 Regarding MIN_DNS_TTL, Microsoft Windows used (still does?) to have a
 minimum TTL of 15 minutes for it's client-side cache, IIRC.
 Given how prevalent that platform is, I guess a 1 minute MIN_DNS_TTL is
 very unlikely to break things.

 Are there plans to allow more values than {MIN,MAX}_DNS_TTL?
