Not yet, for the simple reason that the spec isn't stable yet. We're doing an early feedback launch soon, I can notify if you want. We'll put the reference implementation on GitHub, too. One of the things that's important to me is the option for "3rd party software" to participate in the network as well, so we're keeping it as simple as possible to enable others to build stuff that integrates with it.
