So a application should be designed in a way that it can also be run  
on top of other Linux systems. Every communication to a application  
located outside OK Linux should be implemented using drivers. Do I see  
that right so far? Is there any example out there I can take a look at  
how it works in detail?
But how can I see some output of application running outside OK Linux?  
How can I know which process running directly on top of the L4 kernel  
or start / stop them?

There I have the next question. I know pistachio is the L4 kernel and  
wombat the OK Linux right? But what is iguana exactly?
