I like MaraDNS. It's light, fast, and secure. But I have 2 problems with it:

1. It's static. If I need to change a zone definition I must restart the
service. I know, that'll take less than a couple of seconds, but I don't
like it. (Yeah, I'm anal like that :-P )

2. I couldn't really figure out Deadwood. AFAIK Gentoo has no Deadwood
package, and I need Deadwood to solve "dangling CNAME" problems [1].

Yes. With PowerDNS, I think I will run a nohup-ed script that 'wakes up'
every a couple of minutes, do some ping tests, and update pdns' MySQL
database.
