Using multiple servers. Not for load distribution/backup? #39

Thank you for building such a simple, yet powerful signaling server. It will surely help many people build WebRTC apps with ease.

I tried the very basic example listed in the README.MD The given example works well, however, I have some concerns.

I tried with 4 signalhub servers.

var hub = signalhub('my-app-name', [
'http://localhost:8080',
'http://localhost:8081',
'http://localhost:8082',
'http://localhost:8083'
])

Additionally, I called broadcast every 5 seconds.
```
setInterval(function(){
hub.broadcast('my-channel', {hello: 'world'})
}, 5000);
```
Problem I receive the message {hello: 'world'} 4 times, every 5 seconds... I expected it to be received only once every 5 seconds. From the documentation, it looked like the other servers are used as a backup or maybe act to distribute the load. Additionally, looking at the network requests, I saw that the client was connected to all the servers. Doesn't that somewhat defeat the purpose of having multiple servers? Am I missing something here?
