Dear Thomas;

Instead of talking of big things starting a
Sub-Sub-Distribution would be great thing.

If you are seriously for such distribution
we can discuss this topic on a new mailing-group.

Well I even don't know how to do it, but I am
really interested in it and would like to be
part of such effort. (May be I will learn
from the process)

I feel that you already know Varkon people
and might be able to set ball rolling. I am
already interested keep me informed
about the progress.

Though XFCE is great I thing FluxBox is the
lightest of the Desktop environment, I have seen.

I think the focus should be having as most as possible reccources left for
CAD application('s). For this I would vote for a lightweigt window manager,
e.g. XFCE.
If such a CAD Distribution would be based upon XUbuntu the questions which
kernel, hardware or display is mostly obsolete due to the fact that this
would be given by XUbuntu. (BTW: that's why I had the idea of a
sub-sub-distribution. one sub for CAD and the other for XUbuntu :-))

Varkon came up during the starting thread and because till now it is the
powerfull I'm aware of. So it might be better to use the term &CADapp
of Varkon. I would be very glad if we have more Distributions which are
tailored for specific company branches. :-)

This often has 'historic' reasons or because of special threngtheness in
or the other technical / functional aspect.

AFAIR Varkon was originally developed for SAAB a well reputated aviation
industry company from Sweden. So this is also the reason for Varkons
in freeshape surface design which is a must for developing an airplane.
Catia can be found in a lot of automotive companies, e.g. Dymler Chrysler.
Other CAD Environments have their historic roots in electrical engineering,
e.g. Eagle or in the architecture, e.g. AutoCAD. You will find others for
moulding design, optics design, ..., ..., ....

On the other side the big number of applications for one and the same task
GNU/Linux is also an argument for (Branch)tailored sub-sub-distributions.
Under the aspect of winning world domation this would make it easier for
interested people to get into contact with free software in professional
environments. For them it would give (or is it would be? Sorry my rotten
english) some kind of 'proof of feasibility'.

The listing of aplications you gave in the paragraph above is often asked
one gets in contact to professionals, e.g. at a GNU/Linux booth on fairs
trade shows. A lot of theese people are irritated by the big number of
applications for the same task in GNU/Linux. It's the classical 'not to see
the wood for the trees' phenomenon.

We are not on a Debian list...

And not to forget discussion is the first step before planning...
