Probably not possible but would be a fantastic capability...

Support for Zune

Imagine being able to plug your Zune into a Redfly and watch video on the Redfly screen, and have the Redfly charge your Zune. That would be killer on long flights...

Just dreaming...

Heck, I'd be happy if my Redfly could play video off my Windows Mobile device.

Can the Zune charge through its USB port? If so then you should be able to charge it off the Redfly. I charge my Nokia N810 with one all the time.
