Bottom posting without trimming is more annoying than top-posting. And, if I can do it with Apple Mail on Mac OS X you can do it from your client, too. Thank you!]

Hmm, while it's not CentOS you may want to look at how Scientific Linux does 'sites' (in their terminology). As Scientific Linux is built from the same source RPMS as CentOS is, much of the 'sites' info should be at least somewhat applicable.
See:http://www.scientificlinux.org/documentation/howto/create.site (note that that's currently throwing an internal server error; they run Plone, and Plone has apparently had an issue).
They key is to not run afoul of the CentOS trademarks, if you use a CentOS base (if you use an SL base, their usage guidelines apply, and they are different from the CentOS ones I'm sure). And, as always, I reserve the right to be wrong, and Johnny, Karanbir, or other CentOS dev is more than welcome to correct me if need be.
