	Ok, I've tried grasping what you are telling me here, let's see how far
off I am now... From the example in 9.5.5.1:

# tc qdisc add dev eth0 root handle 1: htb default 30

# tc class add dev eth0 parent 1: classid 1:1 htb rate 6mbit burst 15k

# tc class add dev eth0 parent 1:1 classid 1:10 htb rate 5mbit burst 15k
# tc class add dev eth0 parent 1:1 classid 1:20 htb rate 3mbit ceil 6mbit
# burst 15k tc class add dev eth0 parent 1:1 classid 1:30 htb rate 1kbit
# ceil 6mbit burst 15k

The author then recommends SFQ for beneath these classes:

# tc qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10
# tc qdisc add dev eth0 parent 1:20 handle 20: sfq perturb 10
# tc qdisc add dev eth0 parent 1:30 handle 30: sfq perturb 10

Add the filters which direct traffic to the right classes:

# U32="tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32"
# $U32 match ip dport 80 0xffff flowid 1:10
# $U32 match ip sport 25 0xffff flowid 1:20

	If I started with something similar to this, then I would just start
building under the 10:, 20:, 30: for the different IP's? If that's the
case, then I would send all of x.x.x.x to 10:1, and then have the
different rates and priorities within th 10:1 block? Am I on the right
track, or completely out in left field?

	I can never find anyone in there, lots of names, no responses :(
