        Whenever I did the cost of deploying and managing fancy QoS 
and compared it with the cost of getting and managing more capacity,
it was always MUCH MUCH cheaper to get and manage more capacity
than to mess with more QoS.  

        Other folks mileage might vary.  I'd encourage folks in 
that situation to fire up a spreadsheet and do the math.  The
critical variable in my cases was accounting properly for the 
increased ongoing operational costs of maintaining a QoS-enabled
network.  Those turned out to be quite high.
