Now here's what would be awesome: If I could share a window in my text editor / IDE with someone else on the planet, edit a piece of source together in real time, and still be able to save and compile directly from within the software. Oh, wait...
Emacs, of course, has supported this since a long time when running under X Windows. See e.g., "New Frame on Display..." menu item under File...
Yet TFA provided examples of 3G disruptions.
I for one can easily imagine scenarios where our mobile networks are heavily degraded due to viruses on phones and maybe even due to subtle DoS attacks between operators! I know there are products where operators actually may drain (very little) of its own customer's battery time to make measurements on its competitors' coverage. It's a war out there. Possibly the radio networks have to be governmentally run in the long run.
I have no idea how hardened the signaling in RRC etc in 3G/LTE is against DoS attacks. Maybe very little energy is needed to fake paging, disrupt calls, degrade bit-rates etc. Don't dismiss the wires yet!
