Multi-User File Transfer Software?

Is anyone aware of a software solution that allows users to monitor other user’s transfer jobs?
Like a multi-user FTP client?

Users need to be able to log on and monitor other user’s transfer jobs and pick up the completed transfer as necessary (or report on the transfer status), but I can’t think of a way of doing it other than providing the users a generic account on the local server where transfers take place.

Auditing would be desirable.
