In time it will come to include both a server and client library, with samples and API documentation.
Alright, so you want to set up your own server? Great! It's as simple as
npm install jrc cd node_modules/jrc npm start
or, for the braver:
git clone git://github.com/nornalbion/node-jrc.git cd node-jrc bin/jrc-server
Take a look at the file config.json.sample if you want to configure things such as masters.
