redis-events 
Publish events between application instances using redis pub/sub If an event is fired locally, the event is only fired once.
Installing
npm install node-redis-events
Usage
var Emitter = require('node-redis-events');
var emitter = new Emitter({
namespace: 'App'
});
// broadcasted to redis channel `App:data`
emitter.emit('data');
// Add a listener and subscribe to channel `App:data`
emitter.on('data', function(work) {
//do work on `work`
});
// Listener is only called once, but is published to redis, which means another emitter could bind to `data`
emitter.emit('data', 'some work');
TODO:
