Sounds reasonable although I'm not sure if I understand
the difference between "scheduling" and "qdisc".

We're lacking feedback on this subject from the users, we hear
a lot from the typical home user wanting to get some control
over his ADSL/cable link but not much from other areas.

There have been some recent additions, mainly Jamal's actions
and my small ematch API. They perfectly serve as a base to
solve more complex problems but are still in a early stage
of completness and documentation.

The current development direction is to get away from big and
complex problem solvers and focus on tiny and simple components
that can be put together to solve problems more individually.
