There's a second very important point that somebody mentioned on the NANOG
list a while ago:
If the local router/net/link/whatever isn't congested, QoS cannot do anything
to improve life for anybody.
If there *is* congestion, QoS can only improve your service to the normal
uncongested state - and it can *only do so by making somebody else's experience
suck more*....
