Local MCX without OS X server

hi in our environment we do not have a OS X server but wish to deploy Local MCX to the Macs so we have a bit of control/management on these devices. i have been able to use the following to set the preference i want to apply to our test Mac, e.g. [i]sudo dscl . -mcxset /Computers/localhost com.apple.driver.AppleIRController DeviceEnabled always 0[/i] the result is shown in System Profiler under the Managed Client section, but doesn't "apply". i've rebooted, the OS has the latest update. … not sure what else i need to do. I would like to create a script with dscl commands (that configures all Macs in a "standard" way, which will run when the image is deployed but not looking so good. i have created a script with defaults write commands (to customise the image) but would like to use the dscl method. any help would be nice. thanks
