I saw the way that Couch uses versions to resolve conflicts, but the
particular use case I have in mind doesn't need to reason with a
sequence of deltas - I am only interested in being able to retrieve an
arbitrary snapshot so that the application can either compute it's own
diff or just run queries against historical data.

And I wouldn't want to misuse a feature for a purpose that it's not
designed to solve :-)
