My New project: A geolocated Dropbox - Exclusive content in exclusive places

Need feedback for new project in Barcelona. What you think abou get a geolocated content (audio, photos,videos, files in general...) just if you are in a place? Yo have your own storage where can be transfered all the data from other people or companies just if you are physically in a place with your mobile. We are working on a app and a web. Pretty sure it's a good idea! Thanks guys!
