After a soak test, it looks like it's working like a breeze in one of my four servers, and consuming less than 10MB of RAM :-)

Note that I had to upgrade the system, and that's because it's showing 1h 25min ... let's see next weekend ;-)

Isn't the Bind DNS server working correctly? We have two options...

1. Use PowerDNS as many people
2. Try #Go language and implement a DNS Auth server by myself

Well, you know, I'm a crazy guy so, two days spent and option two looks great now :-D
