  Impossible.  Broadcasting over wifi today = unsecured (even with 
WEP/WPA on).  A hacker merely has to use the various tools out there and 
 have at it with time and data packets transmitted.

  WEP is like an open-door today = don't even bother using it! It can 
be cracked so fast, it's almost pointless 
(http://wepcrack.sourceforge.net/ 
http://www.tomsnetworking.com/Sections-article118.php).  WPA is tougher, 
but can be done if you have a short password 
(http://wifinetnews.com/archives/004428.html).  You'll really need to go 
with WPA2 + AES, etc.
