This feature was discussed in , but it doesn't look like anything was ever incorporated into the IPython Notebook. Here's a brief overview of the changes: - Display of messages from other clients can be toggled on and off from within a notebook, either using the ``<M-m>e`` keyboard shortcut in the web UI, or through the option in the "Kernel" menu. - notebook.js controls whether messages are displayed through a callback that is invoked from kernel.js when no callbacks are available for a message. - The UI displays ``execute_input`` messages originating from an other clients in new cells at the end of the notebook. Output messages (``execute_result`` et al.) will only be displayed if a cell exists with a matching message ID. Pending design questions: - Should each ``execute_input`` message cause a new cell to be created? - Should new cells be placed at the end of the notebook, or elsewhere? If the latter, what criteria should be followed?

      """Utilities to enable code objects to be pickled.

      Any process that import this module will be able to pickle code objects.  This

      includes the func_code attribute of any function.  Once unpickled, new

      functions can be built using new.function(code, globals()).  Eventually

      we need to automate all of this so that functions themselves can be pickled.
