Class 1:0 is a special class in htb.  All packets queued in this class will 
get pas thru as fast as possible.  Try class 1:1 and it will work like you 
want :)

There is hacked sfq qdisc : EFSQ.  You can configure it so it uses only the 
src and/or dst address to classify the packets and not the ports.  I have a 
local copy on www.docum.org under FAQ.

I think there is a patch for iptables so you can mark packets based on the 
size of the file where they belong to.  But I'm not sure.  If it exist, you 
can redirect big files to a queue with lower bandwidth.
