Although this looks like a good product, I would have preferred if it could run
on a CentOS dom0 / host / server.
And even though you feel that one install & forget about it, I don't. I do
work a lot on my servers, and prefer to use something that I'm familiar with.
And although I come from a OpenBSD / FreeBSD world, and have used Slackware,
Debian, Mandriva, OpenSuse, FC, Knoppix, Ubuntu, Caldera, etc, I prefer to
stick with one distro and know it well. If you use too many different things,
you tend to loose edge.
And since a lot of commercial control panels work on CentOS only, I also know
that my clients knows CentOS by now, and won't really spend time learning
Debian.
