there is no "solution". Would you ask Micro$oft to change their
distribution licence ? :-P

There is a probability that the F-CPU licence will change
if we get advices from legal experts : GPL has a few drawbacks
but it's the only working licence that we know. Later, a F-CPU
licence will cover the dark corners of RTL source code (all the
problems with the meanings of "compilation" and "linking" that
is different in our case), but i don't believe that our basic
idea and understanding of "freedom" will change.

how much chocolate could i buy with 100K DM ?

We do not "only" focus on the CPU : For example i am both
a programer and electronician (rather loosy both) and i have
remarked that the CPU is the center of both worlds. This is
why my efforts are in this direction.

Concerning your reasons (I/O, programming model etc.), assume
that the CPU is the center of the computer. If the CPU is not
free the rest will remain crappy. OTOH, putting a "free" CPU
in the middle of a "non-free" HW won't solve everything

Ok, i will let others answer (i've seen nicO's answer
and i fear a flame war...).
