A sample implementation using websockets instead of polling is here:

https://gist.github.com/3875846

It still requests the file, which causes a delay.  I think doing a png 
diff sounds like a great idea.  What if we also transfer the png diff 
over the websocket connection (maybe in a binary frame)?
