Callbacks through redis to make cross-server calls a breeze
$ npm install redis-callback
This is an example with two servers, one will call exec and wait for a callback, the other will listen to an event and callback with a result.
This happens over multiple servers. This means you can have an infinite amount of worker roles listening for data to process, and it calls back to your main application server seamlessly.
Awesome, right? :-)
