   Well, some industries don't really have changing product lines and  
increasing numbers of employees.  I'm told (by someone who knows)  
that VMS is very widely used in the steel industry for controlling  
large plants (of the type for which downtime becomes unbelievably  
expensive), and for handling SMS messages in mobile phone networks,  
as two examples.
