Moving right along. What can be sent out over the USB port? Scenario I'm thinking of here is if I want to build a dock (since Nokia is not going to have one available as a standard accessory), I've got the USB port on one side, the AV port on the other. Can I pipe A/V out through the USB, or would that require USB host or USB on the go, (which when I last searched was either not available or couldn't be certified because the certifying agency will not certify a port to charge and be host).
