Reply to control mp3? (warning: pointless)

I can't believe of any actual reason for anyone to ever do this, but it's an amusing idea, and I'm morbidly curious as to if this is possible. This cheap $100, "media player" got me believeing...

In theory, if you ripped the audio from a control CD, put the mp3 on a flash drive, played it on this thing, and ran the sound into a traktor/serato box, you would have an ultra high-resolution standalone deck controller for 100 bucks. Would this work?
