I was hoping I'd hear from the folks at Peachtree about a means of doing this. With the iDecco, they provide a dock that plugs into the iPhone/iPod dock connection. They pull the digital signal off of the device to feed to the iDecco. It would seem a cable, with possibly a small box with a little bit of electronics, could be used instead to plug into the iPod (iPad) dock connection, and then output USB, which could then feed into the Nova. Surely they considered that design option before the decided to build the iDecco. Maybe the amount of electronics needed required too much electronics... Hopefully Apple releases new hardware soon and this question becomes moot. In the meantime, I'll just have to wait to purchase the Nova and D5s.
