just one little point (i'm glad i don't have to give a setuid lecture) personally
i would make sure that the location of the check file is extremely secure.
under normal circumstances, any user could write the rreboot file and cause a reboot
also, remember to remove the file again in rc.local before cron starts etc.
but i like the idea. its much more secure (from a web perspective).
