I shouldn't be saying this, but.... If your kids are using KDE, then there are 
an entirely new level of things you can do to mess with them using DCOP.  
Quick example: I want to log in remotely and force a switch to the next 
virtual desktop.

1. ssh yourkid at remote
2. export DISPLAY=:0.0 (or whatever)
3. dcop kwin KWinInterface nextDesktop

You can browse all DCOP commands for running apps using the 'kdcop' utility or 
on the command line via the 'dcop' utility.  Also, check out this page for 
more info:

Nearly every KDE app exports nearly all of their functionality via DCOP 
commands so your options are almost limitless.
