Is there any plan to make flights more interactive using smartphones? This question might be a little bit off-topic, but I'll give a try.

Me and many people are aeronautics "aficionados" that would love to know about flying data during flight. Today we all have smartphones that run apps for everything: why couldn't airplanes have an internal WIFI for only broadcasting flight data for being displayed in our smartphones (i.e. as if they were cockpit simulators) as well as video streaming from external cameras? Of course this kind of internal network's purpose would be to broadcast data, so security wouldn't be an issue.

Does anybody know if aircraft manufacturers plan to develop such kind of project?
Actually some airline did it already.

Many Airways including Qantas, Virgin American, Delta, Lufthansa and DragonAir (but Cathay not) has installed Wireless inflight entertainment system which allows passengers to access entertainment system and track flight via their mobile/tablet.

Surprisingly some LCC like Virgin Australia and Southwest also provides wireless on-flight entertainment system, though some contents is not free of charge.

On the other hand, several airline use Tablet to replace the original inflight entertainment system in upper class like La Compagnie (All business class airline), as well as some paid onboard entertainment services in LCC.
