Sounds kind of interesting, but when I go to check it out I find out that IPython 1.0 has not been released yet. Couldn't you have waited to make this post untill it was actually available? You're missing out on installs this way.
However, if you'd like to try out IPython 1.0, it's an open source project. You can checkout the latest code at https://github.com/ipython/ipython
