[IPython-dev] Running IPython Notebook against Python 2.7 or Python 3.3

I have loved working with IPython Notebook, but I've become totally
confused about how I set up my main system. I love how it is set up now; I
can start a virtualenv with ipython, that either uses python 2.7 or python
3.3. But if I try to build a similar setup on a clean install of 12.04 from
virtualbox, I can't replicate my environment.

I am not tied to using virtualenv for ipython, but I do need a reliable
setup that lets me choose to use ipython notebook with either Python 2.7 or
3.3. I've played with virtualenvs, with pip and easy_install, with symlinks
from python and python3.3 directories, with dist-packages and
site-packages, and it's left me pretty confused.

Can someone suggest a straightforward way to set up an Ubuntu 12.04 system
to use IPython Notebook, so that I can choose to have the notebook using a
Python 2.7 or Python 3.3 interpreter at different times? For context, I am
working on some tutorials that reference both 2.7 code samples and 3.3 code
samples, and I'd like to be able to run both. I have an open question on
stackoverflow about installing ipython notebook to a virtualenv, but I
don't need that particular question answered necessarily at this point if
there is a better alternative.

(so question) -
