Ok, so "DISPLAY=localhost:0" preceeds the program call.

Sure it can.  It can check for the existance of locally running XWindows 
sessions; can check to see if the call is remote.  It would be a very 
reasonable assumption that the display should be the local default display 
unless a remote display is specified.

Realistically, how many Linux systems actually run multiple display sessions?  
I know the capacitiy is there, and I know that it's used in some 
environments, but the majority of Linux installations are single user, single 
display systems.
