Agreed. From all Pioneer hardware that I have, the DJS-1000 is actually the best device, it is a beast (in a positive way). It deserves more attention that it currently gets. In a previous topic, I was referring to Ableton Link (which became an open protocol) as a possible future feature.
I'm pretty sure there are other nice features that could be added as well, but I don't have insights in the economics / business side of things ;)
