AFAIU, Combinator doesn't solve the problem of twisted.words,  
twisted.internet, and twisted.web being in separately distributed  
packages. Of course, that's "only" an issue while developing, because  
on install, you either use setuptools magic or else install  
everything into the same directory hierarchy.

As an experiment, I've tried rearranging my local hierarchy with  
separate dirs for each project, as follows:

Then, created a wrapper to combine them:
> import os.path

> __path__=[os.path.abspath(os.path.join(os.path.dirname(__file__),  
> "..", elt)) for elt in __path__]
> import copyright
> __version__ = copyright.version
> from twisted.python import compat
> del compat, os

With this setup, things seem to mostly work, besides twisted.plugin,  
which doesn't work because of plugins' insane magic. I suspect  
there's some way to make that work though. So, I think the  
rearrangement is probably doable without too much pain.
