I'm a big fan of this podcast also. They have had some fantastic guests on the show. and the content always seems to be bang upto date.

For anyone interested, theres a new security podcast been started recently that shows potential called Securabit. One of the hosts is Chris Gurling who some may recognise from Hak.5
And while i'm on the subject, a podcast i'm really hoping takes off is Armored Penguin. This ones focuses on Linux Security and Episode 0 was very promising. Links to both are below.
