hi all im working on a coin operated kde controler i have the following

1)a app that runs with decorations of 2048 a on top modal 
2)the app calls darkenscreen b4 showing
3)any change of active status calls refresh darken and raise [efectivly
blocking changeing to other apps]

the idea is that X/kde is started from inittab as a non privilaged user
the screen control software/coin reader runs as root from inittab the
.kderc file is owned by root so global hot keys are deactivated [this is
not a requirement as the app calls the show method as follows

while ((!exec()) && (gotCoin())
  ParinoidInput()

parinoidinput basicaly ensures the screen is darkend and the coin reader
GUI is active and top level.

so killing or pressing escape will not do any thing [killing wont work as
it is run from init as root]

4)the coinreader is polled ever 15 ms while the GUI is active if a coin is
inserted it emits a signal incrementing a counter and allowing the user to
access K or inserting a further coin. 

5)ALT-TAB is active at all times prehaps the honrouble kwm developer could
look into turning off kwm dialogs ect while in darkend mode and running
them top level modal ie logout ect will then be uninteruptable.

6)CTRL-ALT-F<X> this is easily solved by recompileing a kernel and editing
include/linux.h look for MAX_NR_CONSOLES
