Yes, I thought about it, but it will make management a lot more 
complicated. If I have to change rate on one vlan only? At the 
moment:

Up:
iptables -t mangle -A PREROUTING -i eth1.$d+ -j IMQ --todev $d
tc qdisc add dev eth1.$d root tbf rate ...
tc qdisc add dev imq$d root tbf rate ...
ip link set imq$d up

Down:
iptables -t mangle -D PREROUTING -i eth1.$d+ -j IMQ --todev $d
tc qdisc del dev eth1.$d root
tc qdisc del dev imq$d root
ip link set imq$d down

I made wrapper script, which takes device number and shaping 
parameters from command line. I can change shaping parameters on any 
vlan without affecting others.
