Gilles,

You can do that, here and now.
KTempDir uses a default temporary path which is defined as :
  $KDEHOME/tmp-$HOST/...

Default KDEHOME is somehing like $HOME/.kde4 and in this directory
there's tmp-$HOST. It's a symbolic link pointing - by default -
to /tmp/kde-$USER
But you can change this link definition to point to anywhere you wish.
So, all KDE based applications, and Kipi plugins and others, are expected
to honour this.

And if you wish fast access, it can a be a SSD of course, but it can
be RAM, faster than SSD.
(My $KDEHOME/tmp-$HOST points to /dev/shm/kde-$USER
Of course, when using /dev/shm, temporary files will vanish at computer
power off.)
