If all users booted from the same boot server, but pulled apps from different app
servers, would TeacherTool still pick up all users and all processes?  I am guessing
that TeacherTool only picks up processes show as running on the server it is running from?  

How does TeacherTool find users and processes?  Say you had 3 servers in your load
balance cluster.  Could an ssh tunnel be setup in all directions from server to server
so that no matter which server you ran your teacher tool from you could get a list of
logged in users and running apps from another server?

Just thinking that maybe if the processes that are probed by TeacherTool can be tunneled
over ssh maybe it could all be tied together.
