As the original OP of this thread, I love that it's gone 100% off topic
Having said that, I purchased one of these:

and after plugging it into the base stereo and running the cable towards the right leather knee brace panel, and then afterwards, behind that panel, and along the bottom of the inside of the panel that separates the two seats, I'm pretty happy. You can only see about 2" of wire, that looks like it belongs there, does not stick out at all, period. I'll take a pic and share when I get a chance.
I use this with my iPhone, and I listen to a lot of podcasts and other material that is constantly updated/downloaded from online/iTunes.
Otherwise, the idea of an AUX connector with controls, and throwing an ipod into the glovebox, would be great.
EDIT: Here's the pic:
