Hi,

In case there is confusion, my understanding is that the *flask*
version of the notebook doesn't use twisted web 2 at all.  The whole
point of the flask rewrite was to get rid of the dependence on
twisted.   However, so that we could run the flask notebook without
having to setup Apache as dependency, Mike Hansen wrote code so one
can use twisted as the webserver (as a replacement for apache).  I
don't think this uses twisted.web2 at all, but I could be wrong.
Mike?
