Virtual displays

I'm currently using VNC to administer a number of touchscreen machines 
within a bar environment.  I had to change what was on the display of 
these screens whilst the bar was open last week and had to first VNC in, 
disable the touch screen, and then change the running application on the 
machine before re-enabling the touchscreen input and closing the VNC 
session.  All this worked, but I did have to struggle on a few of the 
machines due to people touching the screens whilst I was working with 
VNC before i'd disabled the touchscreens.  I also wasn't happy that 
people could see me working away infront of them.

is there any way to have a secondary screen show up on the host machine 
whilst I'm working in VNC? would a possible solution be to have a dual 
monitor set up - and have VNC use one, and the touchscreen use the 
other? If so, is there anyway to fake this without a dual head graphics 
card or two cards in the machine?

Ideally I'd like to be able to VNC in to the host. have the host display 
an image on the screen and ignore any inputs - mean time i set up the 
machine to what i want it to display, and then when i exit VNC, the 
screen I was working on goes through to the touchscreen display.
