I had a quick look at tramline, an interesting apache add-on, but it still 
uploads the entire file before asking the application server whether it 
wants to accept the file or not.  If the file is accepted it is moved from 
the 'upload' directory to the final 'repository' directory (where the 
application can access it). If the file is not accepted it is deleted from 
the upload directory.
