Thanks, that's good to know. I am planning on taking this course in June in Paris. Like you and ajohnson said, it should complement the CTP course.
I asked Peter by email about the price of the course and his answer was:
At a conference – for example Hack In Paris (France), Athcon (Greece), Brucon (Belgium), Derbycon (US) or HackFest (Canada). Cost is set by the conference organization and is typically somewhere around $1000 USD / 1000 euro
I think this would be a great deal. So I am seriously considering it.
