Spy gear or life-saving technology?

Was pointed to this article about a new single-person glider wing a company has developed by digg.com. It's pretty exciting stuff in that it allows a person to glide to safety from very high altitudes and then use an integrated parachute to land safely:

The technology was demonstrated in spectacular fashion three years ago when Austrian daredevil Felix Baumgartner - a pioneer of freefall gliding - famously 'flew' across the English Channel, leaping out of an aircraft 30,000ft above Dover and landing safely near Calais 12 minutes later.

Wearing an aerodynamic suit, and with a 6ft wide wing strapped to his back, he soared across the sea at 220mph, moving six feet forward through the air for every one foot he fell vertically - and opened his parachute 1,000ft above the ground before landing safely.

As is usual with lots of cool gadgets, the manufacturer designed it with military contracts in mind. The idea being that it could be used by Special Forces personnel for behind-enemy-lines stealth landings.

But wouldn't you feel a little better on your next flight if you knew that the in addition to your seat-belt, you also had a safety device that could be used in instances where the pilot knew that there was no safe way to bring the plane down?

The cost is probably prohibitive now, but mass production for commercial use would make this something that could be standard on all flights in a few decades.
