 This looks like a bug.

 No, no DBUS. There are windowmanager protocols that should work with all 
(compliant) window managers. They are accessible using the KWindowSystem 
class in libkdeui, so one could write a small C++ app for the task, or (I 
assume) e.g. script it in Perl/Python/Javascript using the KDE bindings for 
such languages. There is also a command-line tool called 'wmctrl' that does 
the same, although I've never used it myself.

 As for triggering these actions, I'm not aware of any automatic way of 
reacting to changed monitors. I guess one could create a shortcut for doing 
this manually (systemsettings->advanced->input actions), although that part 
has some problems in KDE4 (I fixed shortcuts too late for KDE4.1.3, so by now 
possibly only openSUSE packages have it, and I don't know if it's been fixed 
for KDE4.2 already).

 There is also the option of adding the mentioned support for scripting in 
KWin itself, but I suppose that is rather an overkill for this specific case 
(although it'd be nice to have it of course ;) ).
