Security with USB Devices

[NewYork User <newyorkuser () gmail com>]

List, 

Does any one know a good program to "autorun" from USB drive on a
windows 2000 or an XP machine? I have tried the traditional
Autorun.inf but didn't have any luck. I looked up in google but
couldn't find any useful stuff. I saw some commercial programs to use
for backup etc..But its not of any use if I want to prove my point
that data can be vulnerable if use of USB drives is not restricted
either by using a program or any kind of security control. I created a
simple batch file to open up a Netcat listener. It is pretty common
for the users lock their machines and leave their desks. I'm looking
for any kind of scripts that can run a batch file automatically or can
copy the data automatically. Any ideas?

Thanks for your help.
