If you want to use classes, you have to choose for htb or cbq.  You can get 
good results even if you are not the bottleneck on the link.  If you want to 
shape the traffic, you will be fine.  But if you also want to give a low 
latency to certain packets, a modem queue can redo what you did on your 
shaping box (imagine that you give an ack packet a high priority but it has 
to wait in a big queue in your modem ....).
