Maybe send a
[;
pd quit(
 message from a patch?

I haven't tried it yet, just looking at the patch to see how it works. I 
notice you use wm withdraw on the root window.

"+#jmz: set kiosk mode (no pd-main window)
+proc pdtk_kiosk {kiosk} {
+    global pd_kiosk
+    set pd_kiosk 0
+    if {$kiosk == 1} {
+            set pd_kiosk 1
+            wm withdraw .
+    }
+}
+#/jmz
"

But in this page at tcl.tk:
http://wiki.tcl.tk/3175
there is a warning not to do that:
"

I wouldn't advise you to use "wm withdraw ." on the "." window.
Under some window managers (especially under unix...) this will prevent 
dialogs that have as parent the "." (like error messages) from showing 
up and block your app. Better to use something like:

 wm geometry . 1x1+0+0
 wm overrideredirect . 1
 wm transient .

You can even send it out of the visible part of the screen, like

 wm geometry . 1x1+3000+3000

But in any case, do not withdraw it :-)


"
Otherwise it looks like a great idea, will it do fullscreen as well?
