I think that'd be great. It's sort of like a super-skins-tool, and it's really nifty. For now, though, I'm gonna stick with trying to put all logic and configuration on the filesystem and only put data in the ZODB, if only because I can't stop and smell the roses for long enough to get cozy with Zope 3 (that stop would be about a year or so for me, as far as I can tell).
