This works for me :

tc filter add dev eth0 parent 10: protocol ip u32 match ip dst 192.168.1.253 
flowid 10:10

The only thing you can do is create a class and filter for each of the extra 
machines.  The WRR qdisc can do this automatically, but I never tried it.  It 
creates a class for each ip-address or mac-address it sees and gives each 
class an equal umount of bandwidth.
