Surly has been thinking about the BSA and has posted a couple of things about the upcoming build. Check out the link and see where he's coming from on the design process.
PS. I've got no idea what Wiley Coyote is thinking up there but since Surly was tossing around the names of Italian motorcycle designers, it seemed to fit. And you should check out The Panelbeater video at Handverker. Also, here's a link to the Brandoli Workshop. Signor Brandoli says it takes a lifetime to learn the skills. Me thinks I should have started a little earlier.
