I presented this at Develop Liverpool yesterday -- similar to what I did at 360idev Devner back in September.
Note: SlideShare seems to have had some kind of fit with the title slides. I really don't repeat myself that much ;)
A lot of the salient parts were made by me vocally. As far as I'm aware there wasn't a recording -- and I don't have notes, but you should get the general idea from the slides above.
There's also a great write-up by Keith Andrew over at PG.BIZ.
