As Aricha indicated, it's certainly possible for Virtual Laser Jockey to create output for more than one projector (which is really more than one zone). BUT, what would happen is that you would get substantially the same laser output on all projectors.
I will remind everyone that QuickShow is meant to be simple laser software, for simple users with simple needs. We admit that QuickShow turns out to be quite a powerful tool, and there are many professional users who are using it. But with QuickShow positioned as an easy-to-use tool, there are certainly limitations to it!
When you need more complexity, then you need a more complex tool, such as LivePRO or BEYOND. In fact, BEYOND has some brand new tools for controlling multiple projectors with virtually just a few mouse clicks.
