[IPython-dev] custom user messages from the kernel

[Jason Grout]

I submitted a pull request to implement custom messages from user's code 
(i.e., from the kernel).  This allows a user to send messages to a 
custom frontend with a new msg_type (so that existing frontends just 
ignore the message, right?).

https://github.com/ipython/ipython/pull/1700

The pull request is more of a request for comment than a request for 
merge.  Specific questions are in the pull request description.  Since 
I'm not sure how to start such code conversations (is just submitting a 
pull request enough?), I thought I'd ask here for comments too.

Thanks,

Jason
