A Good Effort and A Noble Idea, But... (Score 1)

As many have stated already, it has some problems. First off: filtering will prevent most people from accessing most bad things, yes. But the small percentage who do want to access that content, will find ways to get around it. Filtering is sort of like DRM. It really only winds up hampering those it was designed to "protect." You need change attitudes, not implement draconian measures. Remote access? Filtering? Etc? All easily breakable - there are no firmware utilities for Macs that I'm aware of that prevent someone from simply reinstalling the OS - which they can do if they have a Mac at home, or if they know anything about piracy. Not sure what else to offer you, except that what you need is network based filtering, and perhaps a basic set of parental controls (though expect that to be circumvented if people really want to). The problem is, no system that people have physical access to for cracking is terribly secure.
