Business Review: WiFi Hotspots in the air!

Intel and Boeing have signed a deal to set up WiFi hotspots on planes... currently there are 70 planes using this service... few months ago I have read that there are plans to provide mobile phone networks too...So I guess we are not going to hear that " please keep your phones and electronic devices off" thing again.. unless while landing and takeoff of course.
I was just wondering, when the announcement of the option of installing mobile networks on board, was made, there were security concerns by the US intellegance agencies ( about terrorists being able to use the phone for hijacking...etc...) isnt it the same case for internet on board? I guess I can use Skype to voice chat with someone right? or even instant msg him?
