I know exactly the bare brake cable to derailleur cable housing rub you're talking about. My newly built LHT does a little of that, although my derailleur cable housings route down at the traditional stops. One solution would be to install a length of nylon cable liner sleeve over the exposed brake cable, which I also intend to do myself. But as you will see, under normal riding, those cables will not rub against each other.
