Back in the mists of time, when I was working with VAXen and DECnet 
Phase IV, the general practice in our shop was to be careful about 
making MAC addresses generally known.  Seems a quaint habit considering 
the network today, but old habits are sometimes hard to break... and 
they are not always a bad thing!

As far as the security of my home network goes, I get a giggle every 
time I scan for wireless networks at home.  Mine is the ONLY network 
that I can reach that is encrypted.

As far as paranoia goes, one of my mentors once told me that a mild 
degree was a useful attribute for a system administrator.  It tends to 
make one spend more time thinking about what CAN go wrong, which is 
great if you actually put the results into practice.
