Reply to DJ with iPad and Controller

So I took advantage of the free DJ Player for IOS limited time offer and am digging the software. Tomorrow I plan to test the app on my phone and iPad with my brother's Denon MC6000 and also my CDJs. What I am wondering is if there is anybody out there that DJs regularly with just an iPad and controller? Is this a real possibility or is it still too soon. Not that I want to switch or anything. Basically I am kinda intrigued by the idea. I feel Serato or Traktor will eventually work on tablets and would like to use an ipad instead of a laptop with TTs or CDJs in the future.
