As we all know, non-visual binaries have higher density than text
files, or images. Executables and libraries are much like a 2x4:
unhampered, they fall like a rock. (video, of course, falls at a rate
between images and executables, having the surface area of the
individual frame's resolution, but with a whole *stack* of them.)
Anything with higher density than a bitmap naturally needs a parachute
when being delivered from the Cloud, lest they be corrupted on
landing. (Really big images, while not needing a parachute, take a
long time to transfer because of that whole "drifting around like a
feather" thing.)
(Sidebar on damage-detection: md5 effectively extract the "black box"
(the md5sum) out of the delivered data, and detect the presence of any
anomolous activtivity during touch-down. shai, pgp, etc. simply
provide different kinds of blackbox--some are more robust than others.
If the md5 box gets banged up, it *might* not be reliable anymore,
but the pgp boxes are a lot more resistant to damage. At the very
least, you'll always know if a pgpbox was broken on landing, whereas
with a md5box, you're never *certain* that the box survivde while the
binary failed, but it's still a pretty good assumption.)
Advanced systems pair enormous images *with* the binaries -- cutting
out the necessity for the parachute entirely -- of course, if you're
unaware, your local system may not realize that the 'chute is actually
important, and not grant it the care required. This is why you
sometimes download a game and see visual glitches in the
splashscreen--they're just holes in the 'chute.
Finally, fibre networks are substantially faster because they are
effectively transfering files in a vacuum: nothing but light is
involved (no atmosphere from WiFi/3G, nor any pesky copper), and
without resistance, everything falls at the same rate -- 'chute or no.
