But that was such a fun thread!

"Crunchy shell, soft center"?  Sounds like a candy to me...

This is the number one reason for a firewall at most sites I know of.  Most
companies trust their employees, but do not trust the outside world.  You put
your resources where you think the most danger will come from.  If you don't 
trust your employees, then you have lots of internal security as well.  (See
also: banks, hospitals, pharmacies.)
