Be careful about this one Mark.  I could ftp as operator.sys, transfer a
jobstream over and then stream it.  You could get rather creative about what you
put into the job, as well as putting other "supporting files" in the pub area
for the job to use.  Unless you can positively lock out ftp, you have a hole you
need to worry about!
