Not related to git (I hope), but a lot of scientific data/imaging folks seem to think file abstractions are free. I've seen more than one stack explode a _single_ microscope image into 100k files, so you'd hit 1M after trying to store just 10 microscope slides. Then, a realistic archive with thousands of images can hit a billion files before you know it.

It's hard to get people past the demo phase "works for me" when they have played with one image, to realize they really need a reasonable container format to play nice with the systems world outside their one task.
