sync two devices for car play during holidays

Hi,

a feature that I would really love is a sync of video files via wifi.
One iPad is playing the video and has the bluetooth connection to the car.
The other ipad can “see” what file the other ipad is playing and at which position it is.
This way the other ipad can follow the “master” ipad an play the same video (play e.g. from a wifi disk)

Cool for little kids (we have three so where to put the ipad!)
right now I have to do a quick park than press play on both ipads at the same time…

That feature would be awesome because there is no other app that supports it…
No need to buy an dvd/other crap. Can use the existing ipad…

Hope you look into it…

Seb
