i used cat5 in the first incarnation of my CP, works great!, for my newest incarnation i used 25pin scsi cables cut in half and used for quickly connecting and disconnecting, multiple panels, works great, and belkin brand has 25 different colored wires in each which makes for easy wiring, the only hassle is that they ar etoo thin for wire strippers, cat5 is too, you have to use a knife or your fingernails.
