XFree read my mind there, you see the X protocol allows you to request a list 
of toplevel windows. However... as for knowing what programs someone is 
running, XP shows all processes to all users at all times, so if you check 
the process list you will see all the users processes and you will know what 
that user is running. I think Xouvert/XFree could be changed to only return a 
list of the authorized windows though. So this feature is NOT ruled out yet.
