Last weekend I spent a couple days doing the usual marathon of beating my brains out against the wall of debian-cd, and got the following image added to the weekly full CD builds:
http://cdimage.debian.org/cdimage/weekly-builds/i386/iso-cd/debian-testing-i386-kde-CD-binary-1.iso
(Also for other arches of course.) This is a CD that will install KDE instead of the Gnome desktop that comes in the other etch install media. You can get the same effect without this special CD, if you have a good internet connection, by booting a current daily of the installer as follows:
install tasks=kde-desktop
The kde-desktop task may not be as complete and well-rounded as the gnome-desktop task has become thanks to stratus's work, but it should be at least a good basic KDE desktop.
PS, it's entirely a cooincidence that I happen to be announcing this from Germany. :-)
