I've been meaning to do this for a while as well. Break CommChannel and CommChannelMessage out into a separate app. I had them lumped in with objects/models.py due to some funkage with the admin site registering that is now resolved.

NOTE: You will need to syncdb and re-create any channels you may have had. Sorry for the inconvenience, we're still early enough in development where breakages like this may happen once in a blue moon.
