Yes it's called loop hole. The smaller the hole the better the results. The scope does sit higher than the barrel, but it can be adjusted to intersect with the point of impact of the hole, thereby allowing the bullet to zip through.
This presents a set of issues though. The smaller the hole, the more precise the calculation or estimate of the point of impact(read as target aquisition). Since the bullet will intersect the line of sight picture twice in it's trajectory, the calculation must take this into consideration and adjust for it.
The larger the loop, the more latitude the shooter and spotter have of making dope changes out to greater distance.

Try watching Modern Sniper on the Military Channel on for June 22nd @ 10 PM or June 23rd @ 1 AM (all EST) as I think they're repeating the episode that show the US Army training exercise in which they fully describe the technics.
Actually that is where I saw the video. The instructor actually put some black tape around the opening. It appeared to be a slot about 3/4" wide by about 1 1/2" high. The shooter was aiming at at target that may have been around 500 yards. He made the shot.
Sure concealment is part of the technique and yes it is not a new concept. What is different is the size of the whole. Obviously the guy is using a high power scope. It didn't look to see the rifle. Hotguns and Glockmans technical answers are what i was looking for.

The technique has been well addressed. I just wanted to point out that the bullet does not accelerate after leaving the muzzle, it begins decelerating immediately. The rate of deceleration is dependent upon, among other things, ballistic coefficient, air density, and weight.
