Yeah, the wondershaper documentation states this.  The main problem I was
having was that **no** QoS or iptables marking rules seemed to be doing
anything under my newly compiled 2.4.21 kernel (heh, I typo'ed 2.2.21, d'oh).
 Once I got that working, I could instantly see the result from running the
default wondershaper script, and what I have now is essentially a hacked
wondershaper script, with some of mmc's stuff in there as well, with my own
additions (mainly shaping every other IP on my network, apart from mine, to
128/32 <big evil grin>).

(I've found the best option for me for the wondershaper stuff was 3/4 my real
bandwidth - I'm on 512/128, so it's set to 385/96 off memory.  If I download
one file at once, the download speed is about 5-10kb/sec slower - however,
pings aren't really affected, and interactive traffic is snappy as hell.  I
can also download multiple files at once, where the total added download rates
are almost twice as high as they could be before! [previously, one download
would drown out the rest]).

Didn't see that, and it was a seperate thread I started.  I've known about
wondershaper for quite sometime, but I've always used OpenBSD for QoS boxes
(QoS machines I've built in the past have been dedicated machines, only doing
routing & QoS, and I generally always use BSD for this task).

(QoS rocks!)
