Hi Andy, I think that ZPatterns may be helpful for something like this. You could have certain attributes loaded from an exteral method that looks on the filesystem for stuff.. and others in ZODB. It could be configurable via SkinScript. At least this might be a quick way to get something up for testing.... before mucking around in the pickling code.... -steve
