Rental houses are always sticking their logos in weird random positions on camera bodies. The look of Red is obviously something to which a lot of attention is being paid, why not factor in user-added graphical elements into the body, and designate the best spot for such additions? A silly suggestion to be sure, but it might make for a good promotion if you even offered custom nameplates for your buyers - making each camera unique, while at the same time, maintaining the overall aesthetic.
