i don't think it's time to stop now : this discussion has brought
some interesting points and there may be some others to bring.
I also believe that we are responsible enough to avoid "really off-topic"
subjects, even though the evolutionary side of the F-CPU project
is a meaningful element because there are not only technical
constraint : there are social and economical aspects in our group.

It's not much "top-down" but my "development method" is :
while (1) {
  analyse what we have;
  analyse what we need;
  work on what we need most and can obtain;
This is going to last a long time because we are not a company
with paid engineers, fixed budget and professional tools.
Everybody here is free. For example, nicO wants to make his
own scheduler : fine. If i fail to make mine, F-CPU will have
another one. As long as we know where we're going, this is ok.
