Software Assurance (SA) customers, for example, get to run virtual desktops at a lower cost than non-SA customers as part of their enterprise licensing agreement. However, IT shops running thin clients need to buy a Virtual Desktop Access (VDA) license. Microsoft licensing also prohibits virtualizing Internet Explorer, but application virtualization tools -- including Microsoft App-V -- can technically virtualize it. And client hypervisors add another kink in the chain with different requirements as well.
