I have some great news! XeroBank (who offers Internet Privacy, Identity Protection, Privacy Protection, Anonymous Proxy services, Anonymous Surfing, and Anonymous Browsing) has very kindly offered to sponsor MaraDNS. In particular, they will sponsor the implementation of an IP being given instead of a SOA record when someone asks for a host name that doesn't exist.
I will begin work on implementing this today and will release a snapshot (and a second blog entry for today) tonight.
Because of this offer, development on Deadwood is suspended until I get this feature implemented.
