[Zope] File upload product anywhere?

[Tony McDonald]

Hi all,
Has anyone written a file upload 'product' that they'd like to share?

My own requirements are that;
the files should (optionally) go to a file system,
I need to be able to change the interface for the system,
the users should be authenticated from an external database,
the files (if held in a file system) should retain their associations 
with folders (for permissions and access),
and I'd like it in blueberry please.

What I'm basically after is the best of both worlds - Zope 
permissions/acquisition etc. with the 'safety net' of a file system 
for large files (and possible batch uploading).

My problem (or one of them) is that there's no way that I'm up to 
speed enough in Zope/Python to start on this...I have a system doing 
the file upload working well in PHP3, but that (obviously) doesn't 
have the permissions/acquisition power of Zope. I guess I could do 
redirects to my PHP3 scripts from within Zope however, but it's 
hardly (ahem) 'elegant'.

any thoughts gratefully accepted.
