I'm definitely not an IPython1 or Twisted expert (more of a newbie)
and I know next to nothing about the IPython0 codebase, so take my
comments with a grain of salt. My understanding is that this is how
GUI support can be added to IPython1. ipython1.kernel.engineservice
exposes an IEngine interface as a Twisted service. The IEngine
interface provides the functionality of (and the implementation
delegates to) the ipython core. Thus GUI interfaces can interact with
the ipython1 core via Twisted. This is the approach I've used in the
ipython1-cocoa branch to provide a Cocoa frontend for the ipython1
core (i.e. via ipython1.kernel.engineservice.IEngineInteractive).
