Here's something to keep in mind and a little bit of ZODB Zen.
Folders are an *application-level* notion.  There is no visibility
to folders at the database level.  There is no way to look at a database
record and tell what folder the object is in.  An object may not be in 
any folder, or in several.

I envision the database managing quotas and possibly providing 
administrative control based on "accounting" information.  For example, 
one might say that each "member" of a site gets 1 meg of storage.
It doesn't matter *where* (in the application notion of place) that
space is.  They might have 50K in a "news" area, 400K in
a contributed area, and so on.  Similarly, with some future
storage manager, it might be possible for a member to pack *just*
their data.
