Reply to Anyone have any idea if this is possible?

Okay, so my roommate and I both picked up digital DJ-ing at the beginining of this year, he decided to get the M-Audio Xponent, I decided to go with the VCI. I've been getting him jealous about Traktor and found him a mapping for the Xponent that he could use TP instead of shitty ass Torque. With all this 4 deck talk going around I got a pretty cool idea, using his Xponent to control Deck C/D and my VCI to control A/B. The problem is I have no idea how to execute that idea. I've seen the TraktorTools thing that merges TSI's, but I have a Mac. Anyway I believe the TraktorTools thing probably wouldn't do the trick. If anyone has any idea where to start, or has seen it around please respond!
