Virtualization must be heating up, as Microsoft is making some changes to its licensing policy. Business customers can now run up to four instances of Windows on the same PC, which will be a help to cut down on hardware costs. Unfortunately, most of their software (Office) is still licensed on a per client basis, and if you use Windows for your thin clients to connect to your virtual server, that is another fee. Looks like Microsoft is still in the software business.
What I would really like to see is pooled licenses for applications and pooled licenses for virtual server access. This would allow for corps to ramp up and ramp down according to user's demand. This is what green computing is all about, just enough computing power at all times to do the job.
