Some of that code will be useful, but both of these run in user space and 
use the Xorg keyboard inputs. This means that if I have a synth connected 
to virtual kb, as soon as I try to change the synth patch, I loose my 
virtual keyboard access because keyboard follows focus to the synth 
application (which is what we want almost always). That is why I have to 
run as a system user.
