" if you want a fair CPU power based charging model"
WHY _anyone_ would want a MICRO-SHAFT SERVER "operating system" is BEYOND ME.
That goes double with the availability of RHEL (if you need the support), and CentOS (if you can manage it yourself), not to mention every OTHER Linux distro out there that has a lot of support for 'Enterprise' things...
does RHEL do per-core / per-cpu / per-seat licensing like Micro-shaft? Just wondering, as to the best of my knowledge they do NOT.
Then again, I mentioned that CentOS is *free*
