None from me.  Is there a way to do ipython['all'] that gets all of:

pyzmq, pygments, tornado, nose

And eventually jinja, etc.

Then we can also display a message like:

QtConsole requires Qt and bindings, which must be installed separately
nbconvert may require pandoc, latex, and/or inkscape depending on your
usage, which must be installed separately
