From wikipedia (http://en.wikipedia.org/wiki/Bluetooth) :
[Bluetooth] operates in the license-free ISM band at 2.45 GHz. In order to avoid interfering with other protocols which use the 2.45 GHz band, the Bluetooth protocol divides the band into 79 channels (each 1 MHz wide) and changes channels up to 1600 times per second.

bluetooth uses 79 Channels 1MHz each on the 2.4 GHz ISM Band
and hops when it encounters interference.

bt operates in the unlicensed ISM band at 2.4ghz
the hop rate is 1600 hops/second
a point-to-point bt network has 1 channel
while a multi-point has 7

Along with milw0rm (http://www.milw0rm.com/) you should not forget about Security Forest (http://www.securityforest.com). They include a nice framework that provides and index and update scripts.

Larry and Paul,
Great show last week. I especially enjoyed the dialogue relating the number of cats and story time with Nick. I am currently moving into a new position at my company and wondered how each of you guys got your start so I can begin to master the ways of being 1337.
Love the kung fu, keep up the good work.

Hey Gents
just listened to #20. Hey a trivia question that I knew!
Hedy LaMarr, screen name of Hedwig Markey, and
George Antheil received patent 2,292,387 (Aug 1942) for a "Secret Communication System" frequency hopping radio system that was a "security through obsurity" system for radio control of military devices (torpedoes of all things).
