If you're happy with URLs like:

  http://nohost/plone/foo/filedata/bar.tgz

then you could probably use some kind of special traversal
(IPublishTraverse in Zope 2.10+, __bobo_traverse__ otherwise, I think).
 That would avoid you needing to make assumptions about no two file-ish
fields having a file with the same name.
