RE: [RRG] Mobility in the future -- civil aviation mobility

["Fleischman, Eric" <eric.fleischman@boeing.com>]

The VPN requirement recommendation was for air-ground and air-air
communications of devices or systems that have safety importance to
aircraft. 

I am not aware of a security or safety reason that would require VPNing
passenger communications from aircraft. One may debatably want to do it
for non-security or non-safety reasons such as consistency or
performance (e.g., an ATM study has tentatively concluded that there are
performance reasons to use VPN).

Sure - I understand VPNning aircraft stuff (though there's no reason
this can't work with MANET).  I don't understand VPNning
  passenger stuff.
