Great idea but average performance
I intended to use this software to perform an extension monitor by my Macbook Pro 13 for my work PC (windows XP). Unfortunately the software and driver for Windows frozed plenty of times during installation until, after several uninstalls, I could execute it just to face the fact that the text string was broken and replaced by little squares (that way I am never sure what I am clicking).
After a fell random clicks I could stablish the extension. The rendering of the additional screen is decent, besides some blur when you drag a window. The speed and refresh rate are the main problem, since you will never know the exact position of the content of the desktop until some trial and error placements. Another problem is that the app will only work with the native resolution of your mac; if you try different resolutions the windows based program will crash.
