DIY Line Out Cable - Works!

This is great info, and its good to be able to get this much technical information on the inner workings of these devices.  Even better to hear that Sandisk is addressing this further for us.  I do, however, have two simple questions:

  1. Would it be possible to enable line-out without requiring voltage to pin 7?  If so, what are the chances Sansa would allow this with a future FW upgrade, and what (if anything) would be their reasons for not doing so?

  2. Why doesn’t SanDisk want to make a cable?  Seems like it would be a great way to make some extra money, as well as increasing sales to people who buy Ipods instead due to the much greater accessory market.  I can understand that they want to sell their docks for home use, but it would be great for cars, as well as for the portability factor.  Seems like they’d be missing out NOT to make a cable, so what are the reasons against them doing this?
