The money may be in landing some university contracts. Get them to offer it free to students. They could then use it as a marketing ploy for how seriously they take safety. That said, I think the big flaw in the whole thing is the burden it puts on the user to keep it up to date. I'm not terribly interested in having to think ahead about where I'm going, when I'll be back, and to "check in" when I get there. What I'd be more interested in is something like this: It automatically tracks you via GPS at all times. This data is strictly off limits to anyone but you with the following exception. You setup a short list of people as your emergency contacts. In the event one of these people is concerned about your whereabouts. They can send an email to an address which distributes to your whole emergency contact list. If no one knows where you are, 2+ (configurable) people can choose to independently log-in to the service and once enough have used their "key" your GPS location becomes available to them. Also there's no reason the service couldn't become pretty smart about your expected whereabouts (we're all creatures of habit after-all). If you strayed far from behavior it algorithmically expected, it could trigger an alert on the phone (probably best if it was obscure, so if you were kid-napped or something you couldn't be forced to dismiss it under duress). If you didn't dismiss the alert it would notify your emergency contact list.
