That all sounds pretty cool, but it's precisely the opposite of what I'm
trying to acheive: keeping things as simple as possible. Snapshotting is
neat for testing, especially for the type of snapshots that writes
deltas on top of some base. ZopeDB offers precisely this sort of
feature directly, I've read; that's what I'd wish from every database.

Yeah... I'd just hoped to push it further down given that I only have
about a handful entries for each collection.

Cheers. I'll give it another go.
