I'm so glad this thread has really taken off! After seeing all the interest here in the subject (and as my own interest grows into a serious hobby/mild obsession) I've decided to start a blog documenting my research into English Brett strains. There's a lot of info scattered around the web on the subject, and my goal is to condense it on this blog and provide a resource for others who want to learn. If you're a history nut like me, or you just want to learn how to brew these traditional beers, I hope this will be useful to you!
