The problem is, how do you classify your traffic for queueing?  i.e. where 
and how do you decide whether to put a given packet into queue A or B?

In the normal processing path, this happens inside the packet filters 
(either pf or ipfw at this time).  On a given "firewall" rule you can 
decide which queue will be used for packets that match the rule (or the 
state created by this rule).  This information is later used as the 
packet is enqueued in the ALTQ on the network interface.  If you want a 
netgraph node (I belive that is what you are talking about) to do ALTQ, 
you need a classifier somewhere as well.
