Watching ABC news and they're talking about campus security. One option they discussed was an IM-based emergency messaging system. This is brilliant. Companies like AOL or Yahoo or Google or a decent carrier could even provide a free IM account for college students who sign up for the emergency system. It costs the school nothing.
You're sitting in class and 3 phones go off at the same time. These students look at each other. One of them steps up and informs the teacher... This is so simple and powerful, I hope all schools do it soon.
