Exactly! I imagine that it would probably rock the boat over at Pioneer quite a bit.
A friend told me about this the other day, and my first reaction was that I doubt that your everyday DJ is very technical, or interested in Open-Source in general. Of course, I have nothing to back this statement up with, but my assumption is that DJ's wants simplicity, plug-and-play that just works. My friend, who has more insight, and is frequently playing festivals, disagreed, though.
