[permaculture] Shit

Not every home could use this approach or anything even closely
resembling it. How about the people living in high rises, or condo's or
a host of other applications where this approach is not viable. 
When it comes to dealing with the shit issue, it will take many design
solutions that are site specific, there is no one size fits all
solution. Your approach might work if we all lived in a utopian vacuum.

Very good.  Well thought out.  It sounds like this could easily be sized

for an Intentional Community and move a chunk of people off the status 
quo, ecologically insane system all
at once.  What's stopping you from building one?  I hope you do it.
