This is quite off-topic here but still:
On Windows, I have been suggesting for a long time we make
redistributable packages for kdelibs (for instance, "kdelibs 4.3
redistributable runtime") which includes kdelibs and all its
depencencies. The same goes for kdepimlibs and kofficelibs.
Add side-by-side assemblies (
http://en.wikipedia.org/wiki/Side-by-side_assembly ) features to those
redistributables and now you can have kate for kde 4.3 installed and
okular for kde 4.4 installed and you only need a single copy of
kdelibs in your system for all the applications.
We would still have the problem of the third-party dependencies for
kdebase applications, kdegraphics, applications, etc. As creating so
many redistributable runtime packages would be a bit confusing and
tedious to users installing KDE applications, IMHO the kdelibs
redistributable should include all the dependencies for all the
applications in kdebase, kdegraphics, etc.
What I am proposing is certainly not the best solution (it takes an
awful lot of space) but at least it makes distributing a KDE
application on Windows easier than now (the KDE on Windows installer
works very well but it's very confusing to users). It would be a
matter of checking if the KDE 4.3 redistributable package is installed
and if it's not, tell the user to download and install it, just like
Microsoft does for Visual C++ 2005, 2008, etc.
As for updating applications, we could have a KDE Update applet, like
Google, Real Player, etc have (for instance, using Google Update
Engine: http://code.google.com/p/update-engine/ )
There are issues with DBus to implement this approach in case you have
two KDE runtimes installed (e. g. KDE 4.3 and KDE 4.4) but when I
talked about this with Holger Schöder at GCDS, he told me they should
The only reason I have not implemented what I'm proposing is currently
I'm too busy with work. In fact, I would not be able to start with
that until October, which may mean these will not be ready until KDE
I don't know what's the situation in Mac but I guess a similar
approach (distributing 2-3 huge packages with all the required
libraries, daemons, etc) might also work.

AFAIK, most applications will tell you to install the latest JRE
version from Sun. Only a few dinosaurs (OpenOffice.org, Oracle and so)
would install their own version.
