Thanks... this sounds a lot like what I'm after :-)

Well, I don't mind the 'skins' being stored in the ZODB, but, as Steve A
mentioned, I _would_ like stuff created in the RDBMS to 'magically
appear' in the Zope side of things. I guess that means FwCS and
folder-subclassing DataSkins are a no-no?

They may each have mutliple parents too ;-)
The point for me is that the id (context_id in your example) is unique
in terms of _only_ the following constraint:
No parent may have more than one child with the same id.
This is actually how the ZODB works except that it objects in the ZODB
may only have one parent (well, at least ZODBs managed with Zope ;-)

might be better if it resolved a path into an object, like Zope does,
hence my keenness to see if there isn't a simple way I can make Zope and
Zpatterns do the bulk of the work, just with the tweaks I need...

Hurm... I'd love them to have a UI identical to normal Zope
folders/objectmanagers, though, with properties, a security tab, and, in
a dream world, the ability to drop normal DTML methods, python Scripts
and the like into the foldersish objects.
Is this asking for too much? ;-)
