Nope.

You'll have an AD structure with a domain called "ohio".  The
confusing part for me is the use of the word domain in both cases.  As you
say, they are completely different, so calling both domains is confusing.

I don't know, my AD experience is with DNS running on W2K or W2K3 servers. 
 According to MS the DNS server must support RFC 2052 and
RFC 2136.  They specifically mention W2K/W2K3 DNS and BIND 8.1.2 or later.
