disable iSight camera

FYI- I edited so hopefully it won't just show up as a new thread... We purchased some new intel macs which come with a built in iSight camera. Currently there are at least 3 programs installed by default that directly make use of the camera - PhotoBooth, iMovie, and Quicktime Player. We do not want kids using the cameras but we will need to be able to use iMovie and Quicktime. I had heard that you could just remove the kernel extension to the camera (/System/Library/Extensions/Apple_iSight.kext) to disable it and after a reboot this seems to have no effect. sudo rm /System/Library/Extensions/Apple_iSight.kext I thought maybe the extension was just being cached so I tried touching the Extensions folder which supposedly causes the cache files to be recreated at boot: sudo touch /System/Library/Extensions and a reboot but no luck. Tried a bigger hammer and just removed the cache files: sudo rm /System/Library/Extensions.kextcache sudo rm /System/Library/Extensions.mkext sudo rm /System/Library/Caches/com.apple.kernelcaches/* No luck this time either....my face keeps appearing in Quicktime. Anyone have any other solutions? I would prefer a software solution, rather than duct tape or super glue :)
