I think djb is a brilliant programmer, and he has written some absolutely fantastic code, but I also think that he is becoming less and less relevant as time goes on. Various DNS servers have massively improved, security is being taken more seriously (due in part to him, no doubt) but his software doesn't seem to be moving forward...

dnscache for example doesn't (at least in my testing) connect over IPv6 to a remote name server to resolve a domain, nor does it do DNSSEC validation (and I understand DJB doesn't like DNSSEC, unfortunately it is here and I think that more and more having a validating resolver is a good idea).
