Jeremy, you should play more often with with the Paparazzi system.
The "launch" button just sets the launch variable in the autopilot, 
which enables the throttle (main_ap.c:361). It is the button which must 
be used for real takeoff in AUTO2 without RC.
The "launch" button in the sim applet sets the ground speed to the 
nominal speed. Because it is greater than the 5m/s threshold 
(main_ap.c:453), the launch variable is also set to TRUE, enabling the 
throttle in AUTO2. So it is required to push only one of these two 
buttons in simulation.

No Jeremy, one more time, nobody will get into this debate. Martin, 
don't reply !

On some other operating systems, you have to reinstall the driver each 
time you plug the cable on a different USB plug. But you don't require 
any admin privileges to do it, so it does not really matter.
