You probably should only have ONE domain -- at most a few.

These should be consolidate -- either initially or ASAP.

That's more what domains are far.

That's completely separate from Domain design. You can stop
that just by using the conditional forwarding but must use Win2003
for conditional forwarding or one of the other methods.

One mistake you may be making is in designing all three ideas
at once.
Domain design comes first, then SIMPLE DNS design, then optimize
for efficiency and control.
Mentally separate "resolving for YOUR RESOURCE" from "helping
your clients resolve including the Internet" -- they are really two
different
jobs even though many DNS servers will do both for efficiency.

Sure.

Win2K and Win2003 support the same records so it isn't an issue.
The Win2003 DNS servers have more (operational) features.

It could but that's not the default or built-in to ANY DNS server -- you
would do that with conditional forwarding or cross secondaries or stubs.

I can make it work with any of them -- it's much easier with Win2003.

Or a few -- how many really separate companies do you really have?
(but still in the same resource sharing environment)
How many security account policies (password, lockout, or kerberos)?
How many political issues where the admins INSIST on owning their
own resources but still want to be part of the forest/truth relationship?
It's those last three questions that determine ALMOST EVERY domain
boundary.
