this won't work in the real world b/c even if you solved the problem of
"similariy" knowing different files are really the same piece of music; but
once you ownloaded it, media players would have to read what was created and
translate it. Different encoders encode differently;
but, then there is things like bit-rate for mp3s, etc...say the first part of
my mp3 is encoded at a high bit-rate interleaved with low-bit rate encoded
data; now, write the mp3 player to handle that.
This also could not be used in comerce b/c people want high-quality,
loss-less, media, they're paying for it; while this would return on "similar"
which says to the customer, "well, I know what you want, but you have to take
what you get."

Even a movie with different translations would have non-matching 16KB chunks
because audio and video frames are interleaved. Unless you have separate
audio/video channels, I don't see how this would ever work.
Furthermore, different rips of the same CD track are likely not identical
unless the codec happens to be exactly the same. (Is this true? I'm not
sure if there is homogeny between MP3 encoders.)
As for software packages, the contained files are generally compressed,
throwing off all similarity. And even if not compressed, unless they are
perfectly byte aligned (a 1 in 65536 chance), they won't match up.
So I just don't see how this would work in the real world. Am I
misunderstanding it?
