Somewhere I read that a while ago...will make notes about that, thank you.

Webservers are used to upload video and audio conferences and even stream
them across the LAN and access SugarCRM to download/view reports, etc.
If we use only one M$ exchange server sometimes gets bottlenecked with all
those kinds of mails sent. avi's mpeg's videos, wav's, mp3's, excel and
powerpoint docs, etc.
But we have 2 backups that can handle all just fine, so we're trying to
replace them with a Xen cluster based on Centos and postfix.

We're not using windows under Xen, we're trying to get rid of M$(reducing
licensing fees mostly).
We use CentOS for SugarCRM and Debian for DNS, but want to use CentOS for
everything if we could.
