...and how I wanted to delegate via NS records, not a CNAME. This may
have been in the second message, in order to clarify what I was saying.
Either way, I said it.

We manage countless other tiny details regarding UNIX, networking 
equipment, load balancers and god knows how many other things in order 
to keep our web services running. We can keep glue current. We do it in
our DNS already.

This is NOT like the gTLDs delegating www.lycos.com, but the lycos 
nameservers delegating www.lycos.com. You're sliding down a slippery
slope here, I've implied no such thing.

Jim, obviously we should contract your company to run our DNS. Oh, no
wait, your company allows random shmucks to call up and register their
nameservers as popular domain names used by my company. Nope, we'll run
it I think. You guys have cost us enough money.
