I have little experience with actually, formally, consciously separating 
presentation from business logic - but this Open Access initiative seems 
like it could support that concept nicely - same code in RPG can be 
pointed at one of several presentation devices and still work - business 
logic does still have to request presentation, right? Am I off base in 
my understanding?
