Seems simple enough to do, I was actually starting to think about iPod integrating since even a full blown car PC still won't stop people from wanting to plug in the iPod. Would be a handy feature and what you suggested is actually a great idea. I suggested the alternate menu if you want to control the iPod with RR, which I am curious myself if RR can do that. I am going to check it out.
Your request came at a good time since I can work this into the next version.
