If you still have the mail, this topic was discussed after I posted under:

Hi All !!
Today I came across a typical Hole in Listener Security.
If you have lsnrctl utility (or Database installation) at one
Box, then you can stop the listener on another Box. Just change
the parameter file (listener.ora) to have hostname of another
(may be production server) box. Now goto lsnrctl and fire stop
command. you would notice that the local listener is running
but the remote listener is down.......
This is more serious issue on platforms like Unix and VMS
where you can control listener (locally) only if you are a
member of DBA group. This means that Listener doesn't have any
cross OS check in it....
Is this a known issue/bug. Any-ideas, any patches? Oracle
Corp guys, what you say?
Waiting for you views......
