IPython has a custom event loop. You'll need to look at it's sources
and figure out how to drive it externally. There's some plugins for
IPython that may help (or may even work out of the box), they're used
to let you run wx or gtk or other libraries that have their own event
loop within IPython.

Are you aware that wx already has a Python shell implementation? It's
different than IPython, of course, but it has graphical inspection of
objects which is the main reason people tend to use IPython.
