An anonymous reader writes "Apple has long had a troubled relationship with IT departments. Any creative professional will testify just how hard it can be to convince IT managers to allow the use of Macs in Windows-dominated environments. And, despite the fact that the Mac OS is now quite a well-behaved client on Windows LANs, Apple sometimes does little to help its own cause. The decision to release OS10.7, or Lion, for download only is hardly going to endear Apple to IT managers who need to conserve network resources. Most of all, IT departments would want to see the Mac OS offering full support for virtualization, on the desktop and on the server. There are rumors that Apple will, itself, run a virtualized version of Mac OS under VMware as part of its iCloud product. Allowing OS X to run as a guest on non-Apple servers, and even on the desktop under VDI, would bring enormous administrative benefits to companies using Macs."
