I have 2 Bullit FTP servers running under Windows XP Professional.
There are just under 200 client folders in each server. The servers
are in two different locations in the same town, roughly 3KM apart and
there is a hertzien link between the two sites. Each location has a
site manager responsible for the incoming FTP files and their
distribution throughout the company.

I am looking for a solution whereby a hand held device will *ring* /
*vibrate* or somehow *signal* the site manager that client X has
transfered/is transfering his files into client X's traffic folder.

I appreciate that the easiest solution is to ask Client X to confirm
their transfer is underway/has completed, but that is proving too
difficult.

Anyone any ideas? Blackberry devices perhaps? If so, would that
require any changes in the existing structure? Appreciate any swift
replies.

Maybe a product like this [ http://www.youvegotfiles.com/ ]

Feature Summary 
At user-defined intervals, You've Got Files!? examines selected
directories and FTP-accessible folders for new or changed files, and
sends an email notification with information on the new or modified
files to a list of email addresses.

Thanks for that. Precisely what I need. Sorry I can't pay you, but cheers!
