Yeah, I realize that... I'm just trying to avoid having to go through
the ISP every time I want a new alias. I don't want to take over DNS
responsibilities for the whole site, but I do want immediate, local
control over my aliases.

It's just a Convenience issue... if it's not an easy thing to set up
I'll just ask the ISP.
