I use a shorter, similar cable when I travel with 2 macbooks (work and personal). I like to use barrier (software kind-of KVM) to share my mouse and keyboard between them and work on one, but use the other one for music and reference material. I get work/personal separation with the convenience of using one mouse and keyboard.

I simply set up static IPs on each one and also setup internet sharing from one to the other. Surprisingly barrier, internet sharing and even charging always works with this arrangement. I only have to connect 1 macbook to wifi and power.
