Check e.g. the "leap motion" device.

It uses a websocket to stream the skeleton tracking data to whoever wants it.
This I consider a good example of the use of a websocket.

IMO a web-gui that needs a stateful server part is suicide (it doesn't scale at all),
and therefor I consider that a bad example.
