This is a very late reply, but I doubt polyglossia or macaronic language
can have anything to do with world peace. It is found in very old texts --
I go as far back as Rabelais, but I am sure this is not the first -- with
no visible abatement of international hostilies.
        Its immediate implication , I think, is that language, no matter
what national version it adopts, is a single, unified entity. No doubt it
suggests other ideas as well.
