Humanure Toilets

I've started researching the composting of human waste. In underdeveloped countries, pathogens from human waste going directly into water used for drinking are a seriously significant cause of illness (and death), so there's an extra incentive to find alternate means to dispose of this waste. What could be better than composting it and using it to replenish the soil? In developed countries, we waste so much water with our current toilet / sewage systems that composting toilets seem to provide a logical and environmentally ethical solution that really can't be ignored, either. I'll be posting more about this down the road once I've done some more reading up on it.
