Not UK based or anywhere close, but I don't think you need to go through all the trouble to redo it.
I will take you up on your offer of slides though, I only asked about the recording because I remembered seeing that Samy Kamkar talk online (though it might not have been at OWASP).
I always feel uncomfortable speaking when my talks are being recorded. I have a particular style that's a little unorthodox to speaking. I get all professional when a camera's around, this also means that I feel less comfortable talking freely about issues that may have wider implications.
I guess that's not so important for wordpress, but I'm talking at DC4420[1] next week on evading antimalware defences and that's not something I'd really want to see put up on youtube for obvious reasons.
Big trust betrayal - happy to set up an equivalent webex for the HN group. I understand that Wordpress is particularly useful for landing pages though, so I'm happy to do something and actually spend more time on it making it better for the wider HN community.
