Given that it is broken, without a maintainer, does not really do more than ssh with X11-forwarding, is not integrated with KWallet and ssh-agent, and seems not to be missed kdessh has been moved to tags/unmaintained/4, and will no longer be part of kdeutils resp. the KDE SC, beginning with version 4.4.
As running X11 programs on remote computers might still be nice to have, e.g. by adding a menuentry with a proper command line for an often run program only available on this certain system (think students accessing some university equipment from home), some replacement including either libssh or KDE Platform integration of ssh-add/ssh-agent will be still welcome. So if you have to offer something, get in contact in time for the SC 4.5 development!
