Also a bit of imagination in relation to the applications it enables.

The "soft" authentication available using a combination of GPS and mobile location technology would be perfect for a global messaging/payments/clearing infrastructure.

Iraq's access - post "apocalypse now" - to global payment systems was (I don't know if it still is) essentially via satellite onto laptops.

I was involved in a bid six or seven years ago for a new satellite based payment system for Iran, but we pulled the plug on the bid when at the last minute someone asked for a 25% "commission".

As I recall, a French system got the contract....
