Haven't had any time to work on that, I'm afraid.  It's not super
difficult, but it does require some knowledge of the networking bits.

You can *sort of* use it already with

!cmd

the only thing that doesn't work is truly interactive stuff that
requires stdin reading.  For now, in a cloud scenario the only
reasonable solution is to ssh into your notebook node and use

ipython console --existing [json info]

after getting the connection info with %connect_info.  Fortunately
starcluster makes the process of ssh-ing into your notebook node
completely trivial, so it's not a completely absurd solution.

Obviously in the long run we want real stdin in the notebook, I'm just
offering a temporary workaround.  And if you're not using starcluster
for your EC2 setup, switch to it right away: it will save you a LOT of
time and effort.
