Yeah, and it will open entirely new doors - back-and-forth
communication between editor and IPython.

The machinery that will be used (and exist already) is launching an
ipshellembed from inside Leo (that prints & raw_inputs on the terminal
leo.py was launched from). Any additional IPython stuff I will write
use the existing extension mechanisms (creating new magics, completers
etc.). I don't see much need for IPython 'core' changes, and the stuff
should be portable to future iteration of IPython.

Yeah, there wont be much need to tamper with ipapi (as far as
single-process IPython versions go at least).

I believe even the current IPython would be quite easy to make more
modular, i.e. separate I/O from the execution core.
