I think CueKeeper should be able to take advantage of a new Irmin
backend pretty easily.  Both ends of the connection are using Irmin, the
browser uses an IndexedDB backend, and the server could start using this
new disk-backed Irmin backend.

The key-value API will include details about handling disk barriers,
garbage collection, possibly other things that are not relevant to the
browser.  That API won't aim to be easily reimplemented in a browser.
But Irmin can be, so that shouldn't be an issue.
