Personally, I find little compelling reason to deploy QoS in most 
networks.  Switches may be an exception due to the small buffer space they 
have however.  Even in that case, I'd stick to very simple models.  QoS 
often causes more harm then it does good as it can add a lot of complexity, 
and thereby opex cost, without solving any particular issues that were 
naturally occuring.
