> Wookie currently uses DWR 2, a library that provides push notifications to 
> widgets using a comet-style HTTP protocol. This is used to implement Wookie's 
> version of the Google Wave Gadgets API, which supports collaborative widgets 
> such as chat tools and games.
> However, we should explore other options to provide this functionality, 
> particularly those that offer better performance and added features. For 
> example, we may want to use WebRTC, Web Sockets, or XMPP instead of Comet, 
> and to use operational transform technologies such as Diff-Match-Patch to 
> streamline traffic.
> Other options to consider include using Node.js with Wookie, and deploy 
> Wave-Node and/or ShareJS as backend services. This would however need to be 
> incorporated into the build and deploy process and work cross-platform.
> Any solution should be capable of supporting the existing Wave API.
