DirectoryViews would mean you'd lose #4.
Otherwise, I think they'd work for you and it's a much simpler solution
than ape.

Also, if you have any persistent objects for which there isn't an existing
FSObject-derived version, you'd have to write one.

Another issue is that AFAIK there's no way to control the refresh
interval of FSObject subclasses.  I guess you could monkeypatch
FSObject._updateFromFS.  You might want to do that anyway so you
don't have to run your production servers in debug mode.
