I would guess so.  Otherwise, you may have to significantly rework the
graphics lib to fit into twisted.  I was involved in a project where I
joined cherrypy and twisted into a single process.  I ran each in a separate
thread.  Note that you will need to become very familiar with
callFromThread()---any twisted call you want to make from the graphics side
will need to use this in case the reactor is blocking (e.g. stuck in a
select() call).  Also, if the graphics lib either manipulates or relies on
certain signal behavior, you may need to install your own signal handlers
which do all the processing that both the graphics lib and twisted expect.
 This is especially important if you start any processes from twisted
(ProcessProtocol).

Cheers,

Jason
