What do you exacly mean with "more privileged, higher priority" ??

No problem with cbq nor with htb.

Mhh. I don't understand your point.

Other way. If you create a 1.2 Mbps class, you will send more data then the
internet connecion can handle. So the buffers in the internet modem (most
high-bandwidth modems has big buffers to get a higher throuput) will get
filled.
Solution: make sure the buffers are never filled so send less bandwidth then
you actualy have. You loose some bandwidth, but you win the ability to
control that bandwidth.
There is also something wrong with the output generated by tcng. But I dived
not deep enough in the tcng docs to know what's going wrong.
