Well, more or less correct. What you will need to do use use the
reverse delegation robot:
I'm not certain of what our DNS folks are planning, but basically
we'll maintain the NS records from part of a zone, and send them. So
in the case above, we'd have something like:
97 NS ns1.foo.com.
ARIN gets these records and merges them with the APNIC, LACNIC, and
of course the ARIN records and publishes this to the DNS.

The goal was for management of the ERX space to be as close to
management of non-ERX space as possible. I believe this to be the
case. The only difference you might perceive is a slightly longer (or
shorter!) delay between the time you register your IN-ADDR information
and the time it shows up in the DNS. Hopefully.
