To start, I would recommend the LED backlight as the EL style needs a high voltage power supply. The programming and other controls are easily handled by a Basic Stamp in most cases. (Parllax actually sells a module in their line) They are small so not easily readable from a distance but can be made to scroll messages easily enough. They need to be protected from abuse, bending and shock and are best inside a rugged case with a window. I would not use the RC for data, you need that for important stuff. It might make a really nice handheld data sniffer or interface for an OI.
