[Zope] Renaming File Before Download

[David Siedband]

In one of the web apps I'm working on, users upload files into a 
LocalFS directory.  The python upload script renames the files so that 
the files name is unique, and based on the corresponding unique ID of 
it's metadata in my database.  Though now when people download the 
files they have names like 14201.pdf  instead of the original filename. 
  Is there a way I can rename the file back to it's original name 
(stored in the db) upon download?
