If you subscribe to multiple topics, you cannot define one callback per subscriptions : all callbacks are always called.
Since "jQuery.atmosphere.request" has a "callback" property, I thought it was possible but no, because "invokeCallback" function don't look at it.
I looked at jQuery plugin and I think you can fix it by adding to "invokeCallback" function :

```javascript
if (typeof(jQuery.atmosphere.request.callback) == 'function') {
jQuery.atmosphere.request.callback(response);
}
```

I tested, it seems to work, but maybe it's not the best way to do it.
