I've been following this discussion over the past few days and I think that
there may be two issues here:
1) the rights of "original" code authors to recompense for their ingenuity
2) the use of "fancy" code for doing many of the things that some of the older
programs do once they are "decrypted" for the sake of ease of use while losing
some of the user control.
As far as 1) is concerned, I feel that many authors have been unfairly passed
by, at least in terms of recompense, while making some serious contributions
to the advancements of this field. But in the truest sense of capitalism,
others have collected their work into largish packages and made a few pennies,
while the original author may have been lost. I'm not sure that this is
entirely fair, but does seem to occur in other arenas; witness anti-HIV drugs,
as well as many other pharmaceuticals.
With 2), I used to feel that the user friendly programs should be created for
doing this kind of work, but what I've come to realize as I've progressed
through graduate school that this is both unnecessary, and possibly dangerous.
The science of x-ray crystallography is a very complicated one, comprised of
facets from physics, chemistry, mathematics, computer science, and now biology
/biochemistry. I think that a workshop like the one you have descibed is
fantastic for giving them a flavor, I wish I could have had that kind of
exposure to such a fascinating edge of science while an undergrad. Don't sweat
the small stuff, the data input into SHELXL, XPLOR, or much of the
crystallography software can be quite complicated, reminscent of the science
itself, but they will have time enough to learn it when they have become
crystallographers in their own right.
No flames, please, I am just trying to share a newly found appreciation for the
more arcane style of software that will remain a power for some time.
