The simple way to do it, IMO, is to import a joint module, called
something like cfg.  I just did a little hack in a script with

    cfg = imp.new_module('cfg')

but I don't know how well that works across modules.  I think you'd need
to poke it into sys.modules in order for it to be shared, but I haven't
tested it.

What if there were no rhetorical questions?
