Startup Idea : Computer Availability App

While going to college I realized that half my time would be spent searching for a computer to use at the library. I would like an app that shows you computer stations for a particular location and how many are in use. The app would also allow you to reserve a station once on campus in order to make sure that you have a workstation available to work on. It would also be able to show you your favorite tutors hours of operation and when they are available.
