So if I understand you correctly, after you make 1 agent type per  
script, you would then write a wrapper script calling multiple  
individual scripts for the cases where you want more than one piece of  
data? The approach certainly bears consideration, especially since, as  
you say, the simpler scripts make debugging easier. I hadn't  
originally thought of that approach because I wanted two pieces of  
data displayed in nagios: power state and estimated run time, so I  
just made one script that gave that data. It might be worth breaking  
it down more though. Thanks for the suggestion.
