Last monday I gave a presentation together with adulau on "forensic analysis" at the clussil. You can find his slides on http://www.foo.be/gt/forensic/ and mine on http://www.fruru.com/forensic-20011008. Both presentations are in french (or at least some of it is...)
Future topics of interest might include some wireless stuff or secured operating systems.
