This is a cool new item out for your I-Pod. Will mount on your bars allowing total control of your I-pod while riding. I have found these on 4 or 5 bike sites but they all want $129.95 for them. Link is the best pricie I have found with them in stock in black (found lot's of white ones cheaper then MSRP, but white sucks). With this you can store your pod in your jacket or a bag and fully control it's functions from the remote.
