Using cat >  in a shell script wrapper is the work-around I had hit on 
too.  It
seems to get the job done.  Once I get it all working I will go back and 
rework
mine to use a different filename for each user to eliminate the small 
possibility of
two users colliding. (I say small here because I anticipate rather low 
traffic).
