London Hack (Crack) Day?

Hi all, I went to the HN London meetup and met a lot of really smart people, but felt that the London 'hacker scene' (for want of a better word, given the 2600 connotations) seemed to be more focused on networking than code. After reading a post on the lack of code versus networking at hack days it got me thinking about an equivalent day focused on actual hacks. Being a security geek the term hack has slightly different additional connotations to me, so combining a hack day with low level coding is something I think some might find an interesting learning experience. My question to HN (London) is this: Would any HN'ers be interested in a one day workshop on breaking software - that is, covering the basics of assembly language and memory management building up to writing actual exploit code. As a hack day type event we'd have several sessions where people can learn how to write exploit code, find vulnerabilities in software and so on, and we'd have prizes awarded by a panel for things like the best exploit, most critical vulnerability etc. I dunno, what does HN think? Is this worth doing?
