This is one of those ideas that sounds reasonable until you look at it
from the other side and see how much effort people already put into
preventing just this sort of "spyware". Anyone using it would get
hated real quick.
Also note that (as Andrew pointed out a little later) this model fails
completely when content is downloaded when on-line, but viewed offline
or on a portable device. This is already how the majority of podcasts
are listened to, and the proportion of video watched this way is
(slowly) increasing.
Finally, not everyone uses the official QT player to play even QT
movies. I usually use the free VLC player, for example, whch works
fine for basic video/audio tracks but largely ignores any other fancy
stuff. Other people automatically transcode into a preferred format,
which would also almost always lose such tricks.
Personally, I don't really feel comfortable with the idea of video
files with scripting and "side effects" anyway. How long before the
first Quicktime "virus" brings it all tumbling down ?
