Over at Killing the Buddha, Kind of Like Jews by Gordon Haber is an article about a group of former Messianics who converted to the Noahide faith. The article is a nice glimpse of the modern community of Shomrey Tzedek. The main reservation I would have is that Haber seems to view Noahidism only as a "new" religious movement which he traces back to the nineteenth century Italian rabbi Elijah Benamozegh and his French Gentile disciple, Aime Palliere. But even in the Bible, the book of Acts mentions the Gentile Godfearers who had some attachment to Judaism in ancient times.
