That's up to your operating system. If your OS lets you choose a shell, 
tell it to use IPython. IPython already supports being used as the system 
shell:

http://ipython.org/ipython-doc/dev/interactive/shell.html
http://transneptune.net/2009/06/16/ipython-as-your-default-shell/

If your OS doesn't support choosing a shell, you can't use anything but 
the built-in shell regardless of what Python does.

Either way, this is not a Python problem to solve. It is an OS issue.
