The author talks about Google Cloud Messaging to avoid polling. I've been researching the topic and gave it a try with websockets without much success. TCP connections tend to hang on cell tower switching and I suspect TCP keepalives keep turning the radio on.

I really wonder how to implement push to client on the html5 platform. I even wonder if this is possible at all for now.

cell tower switching is transparent to TCP except for delayed packets. TCP keepalives are off by default and the default interval is 2 hours.
