[Zope] File exchange area - example?

[Ross J. Reedstrom]

Hey Zopists:

As the start of a more general "Collaborative Work" functionality, I
need to throw a quick file exchange area up onto a Zope site. The
download part is dead easy (just steal the 5 lines from
www.zope.org/Download/Contrib !), but the generic upload is a tiny bit
more difficult.  I realize all I need is an appropriate front-end form
to manage_addFile - I'm just hoping someone has a DTML snippet I can
have, to deal with things like: generate a default ID, set the title to
the filename uploaded, deal with name collisions (offer to replace, or
rename), anything else I haven't thought of yet...

The larger project would end up recreating much of the management
functionality of Zope. The problem is the need for a scaleable
interface: The full blown Zope management interface is a wonderfully
rich tool, and as developers, we keep wanting to add more features, but
it's overwhelming for those who need only a limited subset of that
functionality. Hmm, this sounds a bit like the "Content
Managers/Editors" thread.  I see that as one example, the most extreme
case of limited functionality. This (file exchange) is another.

As a second issue, as far as I can tell, permissions are granted based
on Roles. Is it possible to set permissions based on individual Users?
One method I could see is creating an individual Role for each user, but
that could get unwieldy in the management screens.
