Well, we really have five. CDE/Motif, GNOME/GTK+, KDE/Qt, GNUStep and now
UDE. Granted CDE/Motif is not Free, and UDE is unlikely to gain much
momentum at this stage, so it's realistically three or four, depending on
how you count. The "GNOME vs KDE war" has gained so much press people
tend to forget what the real situation is.

Agreed. The CDE vs GNOME vs KDE vs GNUStep vs UDE issue also falls in
this category in my opinion.

Why not? StarOffice's latest version is a "KDE application"; it doesn't
touch Qt, but it does all the KOM and other KDE communications. There is
no reason why a similar thing can't happen with non-GTK GNOME
After GNOME 1.0 comes out, I think it is not only possible, but it would
be a good thing if someone familiar with both toolkits can write a guide
to cross-environment development. This guide would tell a developer how
their application, whether they are using GTK+, Qt, or FooLib can make use
of GNOME features if available and/or KDE features if available,
regardless of widget set.

Actually, GNOME and KDE agree far more than they disagree. We both agree
that we should be using X-Windows, but with an abstraction layer (GDK or
Qt) in case we want to go beyond. We both agree that interapplication
communications should be handled by CORBA. We both agree not only that
internationalization is important, but that we should use GNU gettext to
do it. We both agree that our systems should work on any major Unix, as
well as Linux and *BSD. We both agree that the system should be as
window manager independant as possible, to encourage user choice. The
list goes on and on.

As I mentioned earlier, neither KDE nor GNOME are bound by their widget
set. The only thing you really lose by avoiding the native widget set is
consistent themability. So, if you write a KDE/GTK-- or a GNOME/Qt
program, it risks looking funny, and possibly having some keybinding
inconsistency. Either of these could probably be overcome with some
effort, if it important enough to the developer.

Why? Vi and Emacs haven't merged. Emacs and XEmacs haven't merged. IMAP
and POP3 haven't merged. They don't merge because the community hasn't
chosen one over the other. The community doesn't choose one over the
other because they each have strengths and weaknesses that suit peoples
needs differently. The same goes for CDE, GNOME, KDE and GNUStep.

The core GNOME apps and GTK+ library are written in C. The core KDE
apps and Qt library are written in C++. There is much resistance in both
development community to switching. A code merge is highly unlikely.

Half of your examples already are common. Font handling is done by the X
Server; internationalization by gettext. Themes are dependent on the
widget set, and won't be common unless the widget set is. Screensavers
are trivial. Many components have the same issue as point #1, GNOME will
write their components in C, KDE in C++, merging the code for a component
would be difficult.

Nope. It's the Mexicans vs. the Germans vs. the Bostonians (CDE) :-).

Very unlikely. Keep in mind that these projects both have considerable
momentum. The momentum is not because of a large userbase, it is because
of a large DEVELOPER base. As long as enough developers are working on a
project, it is very very much alive.
Look at GNUStep. GNUStep has almost no press and very little userbase.
In fact a good chunk of their userbase has never heard of GNUStep (i.e.
your typical WindowMaker user). In spite of this, they too have a
considerable amount of momentum.

What I see as probable is (5) the protocols and components become, not
common, but standardized and interchangable. The environments don't
merge, but it becomes easier to support either or both.

Which neither developer base has any motivation to do, so it just won't
happen. As for which is better, people used to GTK+ seem to like GTK+,
people used to Qt seem to like Qt. All this tells me is that both are
effective libraries, and neither has showstopper flaws. So tell me, which
is "better", an apple or an orange?

I have only heard a few users suggesting a merge. I have heard many users
saying that either GNOME or KDE (or in some occasions, both) should go
away (these users often say it quite rudely as well). The only vaild
argument I could think of for either a merge or going away, would be if
one project is hurting for developers because of the other's existance.
As this is not the case in the real world, I don't see any reason why
GNOME or KDE should do this.
> What next?
First, both GNOME and KDE have some immediate issues to be worked out
before continuing on. GNOME is still too buggy and unstable for
primetime, and that is why the feature freeze. KDE still has license
difficulties, and that's why they are apparently seriously considering
switching the core packages to en masse to the Artistic license (at
least this is what I hear from people who read the KDE mailing lists).
After both GNOME and KDE become viable in their own right, both systems
need some fleshing out in features, both can work on new ideas to push the
envelope of desktop environments, and we both should seriously work
towards maximizing interoperability. There's no reason both environments
