Keep all the software controlled addons "off board". Id rather have a laptop in a backpack preconfigured. Make it light!!! KISS principle!- it's worked so far... The camera man can run through the shot and the director/dop can look on a large screen, fine tune the settings, then take the shot. For field work, add a pda adapter that doubles as a touchscreen lcd and keep all the software there. Keeps the camera configured, adaptable and a new industry for software developers....
