At the University of North Carolina at Wilmington, screen locking is
not a problem because of watchdog, a program that logs out inactive
accounts, locked screen or not.  During long file transfers you are 
placed in an exception file that cannot be altered by hand....
ie, if someone tries to put themselves in the file, they don't get
the 'benefits'.  During my stay there this seemed like an effective
compromise.  If you wanted a dawg program for yourself, a fairly
simple way to implement it is to stat your tty for activity.  I haven't
tried this on xterms, but it ought to work.
