    Alienbrain (http://www.alienbrain.com/) does this.  That's
what game companies use for revision control, where data includes
images, motion capture files, game levels, and music, as well as
code.  There's also Autodesk Vault, which does a similar job for
engineering data.

    One key to doing this well is the ability to talk about a
group of revisions across multiple files as an entity, without
having to be the owner of those files.  You need to say what
goes into a build of a game, or a revision of a manufactured
product.

    You also need really good tools to show the differences
between revisions.
