HTB3 is still beta, but fast.  Even faster then CBQ.
For the filters, you can use one fw filter.  This filter will use the 
iptables mark direclty to find the class.  If you mark a packet with 9, it 
will end in class :9.  Very easy.  So all filter logic is in the iptables 
rules.  But you still have to create all the classes.

Or you can use the wrr qdisc (http://wipl-wrr.sourceforge.net).   This qdisc 
will create a class for each ip it sees.  So you don't need to create the 
classes and the filters yourself.
