Red Hat Desktop is such a business-orientated Linux distribution that it's only available in bundles of 10 licences, along with a Linux server and online management from Red Hat. Buy 50 desktops and you get the online management in your building, run on its own server. The operating system is 'closed down' and applications and IT staff can be certified -- an approach that's either 'lock-in' or 'making a business-grade Linux' according to your viewpoint.
