it works fine with virtualenvs, on osx, you can do

    virtualenv env
    . ./env/bin/activate
    easy_install readline
    pip install ipython

on linux, you can avoid the readline install. i have no idea what the windows scene is, but at least for the past four or so years, i've never had a problem with virtualenvs and ipython.

On windows it's the same. Although I think I usually install ipython outside of virtualenvs, because I tend to always use it.
