Transforming a Unused Laptop into a Secondary Monitor

Install ZoneScreen and make the desktop extended to the virtual monitor.
Then, use the ZS Wizard to set up a screen server on my Windows. Run the the client mode of ZS Wizard via Wine on my Linux laptop and connect it to the Windows box.
Note:
1. The latest ZoneScreen 1.0.11.0 did not show virtual monitor on my Windows XP and the SC Wizard did not show the cursor. Version 1.0.10.0 worked fine.
2. TightVNC 2.0.2 did not support projecting only secondary monitor to the VNC client (remmina 0.8.1 with libvncclient). UltraVNC 1.0.8.2 did not show my cursor in the client. RealVNC 4.1.3 refused to make connection.
