@rs666: lol! those blue porta-potties! yeah, not exactly what i think of as an outhouse. those are basically chemical toilets, best i recall.
as for boiling, that might work (i forget what temperature is ideal for killing pathogens), but why? for that matter, how? typically humanure has other stuff in it, like lime, straw, ash, toilet paper, other compost, etc. boiling a 5 gallon bucket (or more) of all that doesn't sound like fun. especially when nature will take care of it just fine, given the time and minimal conditions.
