It doesn't depend at all on any real mathematics. But it does depend
a little maybe on some *cython* code, which isn't pure Python. E.g.,
the misc directory and sage_object.pyx.

You might find sage/server/notebook/run_notebook.py very interesting,
in particular the part that starts:
-----
config.write("""
####################################################################
# WARNING -- Do not edit this file! It is autogenerated each time
# the notebook(...) command is executed.
####################################################################
from twisted.internet import reactor
....
-----
You'll see what from the Sage notebook gets imported when the actual
server is run, i.e., when the twistedconf.tac file is fed to the
twisted daemon script.
Regarding longterm maintainable, what I recommend is:
(1) that you make a new setup.py file
(2) that you refactor a little code in interfaces/expect.py so that
it doesn't depend on the sage math library.
You could do 1-2 after you just get stuff to work. The cool thing is
that with this approach one can just do something like
python setup-notebook.py sdist
and get a source tarball for the notebook part of Sage, and this can
100% coexist with the current Sage library distribution.
