of course, unless you are root on the X-server, or have assumed the
display, and thus the user identity <as was done here> of another, you
should not beable to x-kill just any client.  so, for at least part of
this discuassion and issue, x-kill is working similiar to kill in this
regard.  This is what others are saying as regards the security measures
in place, at least at the time of this 'experiment'.

Thanks,
