Is there a GWT library to interface with the new AppEngine Channel API

I want to use the new channel API on the appengine side. My client is written in GWT. While I could wri开发者_如何学编程te the client side in Javascript, I wanted to know if there is already a GWT library that does that?

I found gwt-channel project but didn't see a whole lot of activity on their project page, so I am not sure if that's the right way to go.
