how to edit .globalpreferences.plist without logout and login?

Question

I want to make a kiosk application in mac. So, I want to disable certain hotkeys which can be done by editing .globalprefernces.plist file but it is requiring a relogin to system and I want to do it without relogin. Similarly as System preferences application do but programatically without pooping the system preferneces applicaiton.

You don't need to edit that file (and should not) to make a kiosk application.

See -[NSApplication setPresentationOptions]. This includes the following options:

   NSApplicationPresentationDefault                    = 0,
   NSApplicationPresentationAutoHideDock               = (1 <<  0),
   NSApplicationPresentationHideDock                   = (1 <<  1),
   NSApplicationPresentationAutoHideMenuBar            = (1 <<  2),
   NSApplicationPresentationHideMenuBar                = (1 <<  3),
   NSApplicationPresentationDisableAppleMenu           = (1 <<  4),
   NSApplicationPresentationDisableProcessSwitching    = (1 <<  5),
   NSApplicationPresentationDisableForceQuit           = (1 <<  6),
   NSApplicationPresentationDisableSessionTermination  = (1 <<  7),
   NSApplicationPresentationDisableHideApplication     = (1 <<  8),
   NSApplicationPresentationDisableMenuBarTransparency = (1 <<  9)

See also Guide to Creating Kiosks on Mac OS X. That discusses the Carbon API for kiosks (which may or may not be available in 64 bit, I didn't check), but there's a clear mapping onto the Cocoa API above.
