OK, as you guys may know by now I'm a massive nerd/geek. I'm currently teaching myself to program Android and BlackBerry handsets/tablets and will be learning iOS later this year, early next year. Anyway, had an idea for an app that would help me learn these things while also may help the mobile DJ. The way I'm thinking it would work is you have a laptop and a wireless access point (make sure you get all the pr0n off the laptop first) that has an app running with you full track list. This app listens for and responds to requests from mobile devices on the wireless network and obviously, the wireless has no internet access. You hand out or display details of the wireless network at the gig and instructions on downloading, installing the mobile device app. For the mobile devices, the user can install a small application that allows them to browse/search your tracklist and send requests to the laptop. On the laptop, you will have a real-time view of requests coming in and be able to sort by most requested, requestor etc. So App On Laptop: * Responds to queries/search requests from mobile handsets * Displays ream-time requests or most-requested song/artist etc App on Mobile Device: * Requests track listing from laptop * Sends track requests to laptop Not saying I'll actually get it up and running but it could be interesting if I do. Any thoughts?
