I'm not sure I completely understand what you want to achieve.

My bad, throwing too much thin client jargon around. I have a wrapper script for the screensaver. I check if someone is using a thin client and if they are I disconnect the session instead of running the actual screensaver. Disconnected sessions remain running on the server until the user reconnects from a thin client (could be the same one or could be a different one). Think Citrix or Windows Terminal Services (I list Citrix first because guess who Microsoft got the technology from.... ;-)

Management wants idle sessions locked or disconnected after 30 minutes. The problem is several users are looking at informantion on the thin client but not actually using them so the idle timeout kicks in and the session gets disconencted. Reconencting is annoying -- it's several seconds slower than just unlocking a screen saver. Thus, this script to warn them before it happens.

Thanks for the help!!
