Hmm - probably not in the first cut. Right now, the only bits I'm
tweaking are:

* how a file gets written to disk
* how a file gets read from disk
* how the sha is calculated, i.e. sha the internal format even
  though the external format is the one on disk.

It's certainly an interesting idea though and one I'd like to think
about more.
