Agree!
50% of success is in good plan!
Requirements, good design - only rest is coding and testing.
I am surprised why this problem was approached from another
end - choice of programming language ??? :)

Sounds almost trivial.

I suppose support for RDBMS and HUGE ZONES is what we need here. If you
have 2,000,000 record zone it takes 20 min to reload it. BIND has an
"rndc" tool which reloads zone files without restarting whole
thing. When you have such big zone you expect many changes to it too.
This problem needs some speacial approach.

IPv6 is would be a small implementation detail, don't make it look like a
major undertaking, AAAA records plus some IPv6/IPv4 migration stuff.
National languages support, special records and extentions which need to
be taken care of. Latest I've heard is an extention for IP Phones.
"www.domain.com" notation is very technical, network - centric, so some
people trying to comeup with more human - readable names, and that going
to be in next versions of BIND. Why I cannot type "Congress Library" but I
have to go and type "dsgdsgf.dsfgdsfg.hfdhdf.gov" ? So most of us ill go
to Google because they cannot remember domain name and then will type it
in browser - why can't we skip this step ?
> Fifth: Rewrite the whole package from scratch to implement DNSSEC.
Yeah! Here is a Huge piece of code which is not the best part of BIND and
sounds like we already have some issues like encryption libraries. Nothing
I know of except thin bindings to OpenSSL.
Also there is TSIG, and SPLIT DNS (when you have all zone records divided
into subsets with different access rules or permissions). Right now this
feature "implemented" by config files hackery and having multiple
instances of BIND running on different machines sharing only parts of zone
records.

Would be nice to have this thing working on MOST unix platforms, so sounds
like Florist can be used here...

Means it also nice to find a _sponsor_ at least for some UNIX hardware and
some network for testbed...
