I just got a tweet from HD metioning his latest presentation wich was about Metasploit 3.2 and the things that are comming with it and I do have to say that it is looking very interesting what will be release very soon. Metasploit has been one of my favorite tools during pentest during all faces of the attack and even helped me improve my ruby code by reading the code in the project. If you can do take a look at it http://metasploit.com/data/confs/sector2008/metasploit_prime.pdf
