Thanks for the suggestions Thadeus. I did think about using callbacks to issue further requests, but I'm trying to keep the overhead down by not establishing additional requests to the server. I mean the connection is already open and waiting, so I guess I'm looking for a way to send partial content to the browser from the controller ideally. If not possible, I can fallback and use AJAX callbacks.
Any ideas on how to send partial content from a controller function?
