down the Internet; the mesh lives on.
If the VPN bridges go down, you're back to mice and pumpkins. There are obvious values in urban-area public meshes, and long distance WLAN, but it's no way to deliver messages globally, even as simple as texting equivalent. The buck does definitely stop when surf is lapping at your toes. What is exactly is wrong with frequent fliers carrying smartphones with http://sourceforge.net/projects/bytewalla/ or similar? http://www.diva-portal.org/smash/get/diva2:541972/FULLTEXT01.pdf
down the mesh? hope you've got capacity for a truck roll to tens of millions!

not true. :/
You need to track a given small, rapidly moving patch of sky in realtime, whether by parabol dish, amateur astronomic instrument, or phased array flat plate or half-dome. The bird is serving hundreds or thousands people ground-side as it passes by. If you really want to jam all these at the same time you'll need a nuke. Taking out the bird from the ground turns a game of cat and mouse, if you're dumping phonesats by the satbusload -- these are short-lived, anyway, and need to be constantly replenished. Orbital denial against small cross-section targets in a really low orbit which can be replenished cheaply will make every country with space access very mad at you, which is dangerous to your health. None of the approaches are mutually exclusive. Use meshes, link them up via VPN tunnels across Internet, use DTN with avian carriers, or phonesats.
