How to use IPython with IronPython

Question

What is the procedure to get IPython to use IronPython as it's Python interpreter?

I know there were previously some issues: http://stackoverflow.com/questions/1160501/what-is-required-to-use-ipython-in-ironpython

But now that these issues should be fixed, how do i actually go about this?

The install doesn't detect IronPython as a version of the Python interpreter, not that I thought it would. But I'm wondering how to do this.

I'd (ideally) like the ability to run both the CPython and IronPython versions of IPython on the same machine.
