Virtual Appliance: VMWare’s virtual appliances are fully configured and ready-to-run software programs—such as MindTouch Deki, shown here—that you can download.
MindTouch Deki was recently used to demo the new VMWare Fusion on MacOSX. I heard from some friends they had seen this in the print magazine. If I heard correctly, I also heard it was in a presentation somewhere. Very cool.
