My last IST-TXL flight on Turkish had a USB jack that one could use to play own movies or listen to own music. Not sure if it could connect Iphones etc.
Cool, may work for Iphones for music, not sure about movies etc.
As long as the USB connected device pressents a file system view to the seat back it should work. I suspect Apple/copy paranoia may interfere. (I had more of a A/V input idea in mind.)
I Movies etc. could be cached locally at seat. Storage is cheap and small.
Totally true and probably do-able, even less a "users device" model than my "broadcast with a bit of cacheing" though.
