ScientificLinux is - in fact - RHEL. So it is not more "cutting edge"
than CentOS...

I See that ScientificLinux has a huge community using it - at least in
Europe. Some big research institutes are using it (CERN for example) -
some projects set it as the default distro (D-Grid - a german GRID
project).
So i don't see you point here ;-)
And in the US, the Tier2 and Tier3 LHC participants are using
ScientificLinux, too. In fact, we've a couple of researchers here who
will use no other distro. you know, like RHEL or CentOS. Too dangerous
in their eyes.
