You can look on lwn.net for articles about unionfs, why its so hard
and why it doesn't work very well yet (and is not yet present in
Linux).

Scott (ex-OLPC, a big contributor to the current /versions scheme)
made some comments on IRC a few months ago that he had
tried(/deployed?) unionfs for litl (in the style that you describe)
and that he didn't recommend it.

Still, certainly something to keep an eye on for the future.
