Doc Example : Better chat.

Have been very interested in this but can't find any good examples out there in regards to the chat. I would love to see an example of how to create a simple chat application using a mobile device and get_server on my remote web server. I'm thinking that example could open the door for many applications such as designing a game service where people using ios and android can both communicate with the get_server backend to play poker, uno, etc.... An example for chat would be all I think a motivated programmer could use to open the possibilities.
