You can with javascript make a call to IPython.kernel.execute that take a code string as input and a callback to deal with the data received back. Or embed in the js string if you already know the data at publish time.

have a look at the following.

I suggest you have a look at user_expressions user_variables also in our doc. 

> So we'd like the functionality for GET/POST in the notebook for our project. And I have one full time student that starts this week. What would be the best way for us to contribute some patches to jumpstart this on the ipython side?

We need to discuss what we want for js<-> python bidirectional communications. More than get/post, people might want to be able to
push data through web sockets. 
There are already been drafts, which were not merge because we were not totally happy with it. 
It is a complex subject, and I don't  think trying to tackle this is the right point to start.

Several people are interested in this, and we really think we must discuss to determine what are the needs
before trying to get any thing done.

For the next few weeks we are focusing on polishing things to release 1.0 mid July, after we will start 
to do what is on 2.0 roadmap, this include javascript bidirectional communications.
