In-flight Internet access takes off
So In-flight Internet is a reality. Or soon will be. One little detail bugs me:
The systems can be configured to enable or disable voice-based functions, and the airlines are opting to prohibit them — at least for now.
This only means that they will block well-known voice over IP protocols on well-known ports or that have well-known traffic signatures. A persistent traveler could still use voice services over a VPN, though SSH port forwarding, or a non-standard port or protocol.
Blocking voice will be hard to do in practice. Perhaps just announcing on the plane that, like congregating in the aisles, voice services are banned while flying, will be more effective and easier to manage.
