Not sure that this is going to help anyone, but since we're on the topic of DNS stuff, I thought I'd throw this out there for anyone who wants control of their domains without having to run a DNS server:

I've been immensely happy with EveryDNS ( http://everydns.net ) since I started using it. It's a free, web-based DNS service. You just point your nameservers at their site and you can then manage all of your domains with their interface -- no need to screw around with nameservers anymore.

I now have nearly 500 records for almost 100 domains on there. While the web interface is pretty janky, I can only remember the service itself going down once over the past year.
