I did a bit of work to my setup and decided to run the cables to the blip box through the same ports that DI2 was setup to run. I attached the 'mount' to the top of the brake cam housing after modifying the mount to fit the shape of the top of the brake cam housing. I clearanced around the sides of the center tab just a hare to fit the cables in. They don't rub or show any signs of issues (fraying, cutting) and I have quick access to the blip box for adjustments. I can also quickly disassemble this setup with a removal of the 4 cables, then a quick 1/2 turn on the blip box to access all the parts to disassemble and ship. Setup time when arriving for IMFL in Nov 2019 was about 25 min for the whole bike. I kept the plugs and caps for all the wires so they're protected when in the bike box.
I rarely need to make derailleur adjustments, but if I do, I just need to remember to think backwards for the whole Front vs Rear thing. Have just over 3200 miles on this setup w/ no cable issues.
