Aha, that sounds like you can just maintain a set of out-of-tree symbolic
links that you keep track of, and let other people (e.g. rsync) deal with
the complexity of managing that side of the world.

And I think you can start experimenting it without any change to the core
datastructures.  In your single-page web site in which its sole html file
embeds an mpeg movie, you keep track of these two things in git:

	porn-of-the-day.html
        porn-of-the-day.mpg -> ../media/6066f5ae75ec.mpg

and any time you want to feed a new movie, you update the symlink to a
different one that lives outside the source-controlled tree, while
arranging the link target to be updated out-of-band.
