Hmm, what is the point of preventing a DoS if you aren't interested
in QoS?  Ensuring that resources are shared appropriately and can't
be "hogged" by one user (e.g. a DoS) are fundamental to QoS, IMHO.
Certainly "rate limiting" and "queueing" are very different from a
policy perspective, but the underlying software is more or less the same.
e.g. I might want to implement Weighted Fair Queuing on a WAN link, while
also limiting specific traffic (like ICMP) to a certain rate.  Or I may
want to reserve a certain amount of bandwidth for a specific flow.
