According to Joe Engalan at VectorForm, a Microsoft Surface Partner, you can. They've created an entry level DJ application that lets groups join in on the fun. This is when Joe's team isn't working on Microsoft Surface with car configurators, presidential election coverage, educational and medical applications to name a few. The DJ started simple, and grew from there. There's even an iPhone app. Now they've added some features like scratching into 2.0.
The first video is Joe and I going over 2.0 alpha (also in HD) and the second video is a demo performance in their offices on an earlier version. Any aspiring DJs out there?
