What would be obscene about that is from a design POV it would be a
waste of resources.
"Music" and "TV" content are from a small number of sources, and
there are a massive potential number of users.
What should happen is instead of transmitting large video files...
block checksums should be transmitted,
and only files that are completely foreign should be transferred.
Whereas everything else being "backed up" is just an assignment of
account access to existing blocks that would
already have been stored on the content servers.
And then also, a user storing 10GB of music would probably take
only a few megabytes of their account space,
once the "space used" is evenly divided by the number of users that
have that block saved,
since a majority of music files backed up would be file-identical
with material someone else had already backed up,
and identical to material already in the iTunes store (which they
could pre-seed their database with).
