Although the concern does make you wonder what you might find on the
Wireless LAN if you did sniff it... hmm ;)

This is also a reminder of the "bigger picture"... you should always
run a firewall on your laptop if you ever connect to a network that's
not your own, and completely, 100% trusted.

I've been experimenting (in a personal, not professional) capacity with
WEP cracking recently, and it's really quite scary just how easy and
quick it is. I managed to crack 128bit WEP in less than 30 minutes.
Scary stuff.

If I ever get a chance to come along to another Horsham meet, I might
put a demo together :)
