Has anyone ever tried using TCP only for a DNS server? I don't know
how well clients would handle that, and I know it has some extra
latency, but if it eliminates the ability to use it for a DDoS it
seems like it might be something worth trying.

I'm assuming that regular TCP-DNS uses one connection per query. Would
it be possible to set it up so it kept the connection up for many
queries, or would that require using a tunnel or rewriting software?
