Git sounds like it should cope well with large objects in the repository, but the general view is that it doesn't perform so well. I wonder why not.
git mmaps the files to access them, and the pack definition is limited to no more than 4G (and since the over-the-wire protocol for download is the same as a pack file you run into limits there)
4G is _huge_ for source code. especially with the compression that git does, but when you start storing binaries that don't diff against each other the repository size can climb rapidly.
this has been documented several times, but it seems to be in the category of 'interesting problem, we should do something about that someday, but not a priority' right now

Yes. Git is exceptionally good at managing text.
Pretty shitty at everything else. Its too bad because I'd like to use it for synchronizing my desktop.

You probably want to look at couchdb and the fuse driver for it.
