Well, if a dedicated recursing database backend and lookup routine would
significantly speed up the performance, then i think we should give it a try,
if the code would be not much different from what it looks now this can be a
configuration option just as well.
I expect overall DNS query rates to rise midterm; keep in mind there are VoIP
(SIP) and E164 about to break through, not speaking of portable uses like
UMTS+EDGE mobile-IP or what kind of an DNS record inflation wide use of IPv6
could mean.

I'll give it another try right after this mail.

Well it's an opensource project after all, how about interesting more people -
and there are many bright ones still out there - to contribute to it?

If Bill Gates had a dime for every time a Windows box crashed...oh, wait a
minute - he already does.
