I have some scripts to do this.  I have a iptables and tc version.  I have a 
scirpt I use to monitor the tc bandwidth and this executes the tc -s commands 
each second.  And generates allmost no overhead.

Iptables can also be used to monitor traffic within a class to see if you have 
to fine tune your htb setup.
