multiple clients updating same file in ftp

[Larry Bates]

Preface the update with a rename.  If the rename fails,
someone else is updating the file, if it succeeds update
the file and rename back when finished.

Suggestion: ftp is not the best way to handle such a task.
Use a database, XMLRPC or sockets is probably a better
way.
