Non-Apple Sherlock 3 Channels?

AnamanFan queries: "I've been a bit curious about Sherlock 3 and the release of the Sherlock SDK. I wondered if there were any new channels out there, but my Googleing came up dry. There are a few nifty developer-related channels by Apple that feature an XPath Finder, as well as JavaScript, HTML, & XQuery interpreters, but I was wondering if anyone out there has made use of the SDK."
