I just want to point out that this may be another use-case for custom
messages in IPython. For example, a matplotlib figure, when it is
drawn, could send the initial png over the websocket as a display_data
message. Matplotlib would then register a callback with IPython to
handle any custom messages coming back from the javascript (routed
according to the parent header). When the javascript detects an event,
it sends a message back to IPython, IPython calls the appropriate
matplotlib callback, and matplotlib has the chance to send a new figure
over. The javascript side likewise has a callback registered to handle
matplotlib's return messages. These messages back and forth may make
sense to have custom message types.
Thanks,
Jason
