AutoDisable/Enable Spaces Based on Monitor Config

This should be very possible using applescript. The script to toggle spaces on and off is pretty easy to do. A good short term solution could be to implement the script to toggle preferences on a keyboard shortcut, then work on getting it to switch automatically based on the number of monitors connected. I have seen something similar with disabling the airport when an ethernet wire is connected.
In the past I have wanted this capability, but I didn't know anything about scripting at the time, and eventually forgot about this issue. (I stopped using spaces altogether as it was very annoying while working with two monitors.) I'm going to try to see if I can figure this one out. I'll let you know what I find.
If you copy the workflow I attached to ~/Library/Services you can set a keyboard shortcut using system preferences. It simply toggles spaces on and off.
