Probably better if I used the term 'weighting' - in WFQ, weighting is only
based on IP precedence (and of course interactive traffic)....
In CBWFQ, you have greater control of the weighting by assigning bandwidth
to anything that can be classified with an ACL (i.e. all 'conversations'
that fit the ACL)

Not true, Justin. CBWFQ allows you to perform QoS per class, not per
conversation. That is its fundamental difference. With WFQ, packets are
classified into "conversations" by a mixture of things, including port and
prtocol numbers.
