How to find busy files when you are _not_ root

Hello,

The following seems to be a kernel task, so I am asking here.

Situation:
Some people upload Files in a certain Directory of a ftp server.
Some of the ftp jobs are very slow.
I have to write a daemon which collects the files which are uploaded
(assumption the transfer alway succeeds - OK thats another topic).
Problem: Sometimes i process files, which are not uploaded (at this
time).

But I cannot determine which files are still open,
(different userids of all users).

I was adviced to use lsof or fuser but this _only_ gives me a
complete listing of all busy (open) files when i am _root_.

Is there another way (kernel function?) which allows my
(not root) daemon to determine if the files are busy ?

Regards
Dietmar
