It doesn't apply to current commercial jets because there is no way to quickly get ready for the jump and get out in time before it crashed. The actual long term goal is not to do high altitude jumps. The long term goal is to get to a point where you can enter the atmosphere and survive that free fall. While Nasa is looking at it for aborting launches, even they know that if you are still in the atmosphere when the systems fail, there isn't much that can be done to save the crew. They are interested in solutions that allow someone to jump just outside of the atmosphere were explosions tend not to happen due to a lack of air.
It's really great for the NASA, but I'm not sure about the required equipment and training making it into commercial flights.
Even if passengers could jump from current commercial aircrafts, most (if not all) would likely die anyway from parachute entaglements or breaking all their bones at landing, assuming you could fit all the equipment required to survive the lack of oxigen and the freezing temperatures.
And then parachutes are frigging expensive to maintain and handle properly, I'd bet companies would rather not go that way.
