Just picked up a RJ45 lan cable crimper on amazon - can find one there or locally at a home improvement store. Get some RJ45 ends, and when (not if, WHEN) the plastic locking tip on your cable breaks, you can cut it off with the tool and replace it. You can find instructions for making a cable easily on the net, or find a nerd with networking experience to do it for you. Also will be easy to make custom length cables, spares, etc... once you've done this a few times, it's actually much easier IMHO than soldering a guitar cable, believe it or not.
One suggestion for the next generation profiler - have a locking end like on the remote on the Kemper side, so the plastic tab isn't necessary.
