very simple datastore reimplementation

FUSE is great, but...

It means interoperability must be an explicit planned-in-advance action:
if a datastore is already on a removable device in your pocket, and you
need to access something on a foreign system, you are stuck unless there
is some minimal level of human interpretability of the file system...

Instead, you have to dig up a system with FUSE/olpcfs installed, and
then copy the files to a conventional file structure.

This is the use case that's hard to get around.
