[IPython-dev] Efficient way to render Javascripts

Brian,

So it seems that for us to get some data from a python object into our
javascript, we write the data to file on the fly so that a js cell can pull
it in from the filesystem or we hard code the data into the js string. Is
that the way it should be done with the current setup?

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?
