Here is a particularly apt discussion of this subject for those willing to explore the issue: http://www.feralscholar.org/blog/index.php/2008/04/29/humanure-composting/

My family and I have been living in Portland and using a bucket toilet for years. With fantastic results. We'd never go back to pooping in drinking water. We've never had a single complaint from neighbors. On the contrary, compliments galore on our great gardens. We shared our story with KBOO radio a few years back: http://kboo.fm/node/3348 and have given presentations on the subject: https://docs.google.com/fileview?id=0BzfzZ9sbmJ-DNGVjNTMyZDMtMWVhYy00Yjk0LTkxNDUtYjg4MWE1ZWM3OTg5&hl=en My suggestion to someone with an open mind: start with saving your pee. It's much easier and the pathogen issue is less relevant. Once you have this going you can take the next step. Here's another thing to consider: wean yourself off toilet paper. Once you've taken this step, you'll never go back. What an absurd concept that one can properly clean oneself with dry paper! We humans are eminently flexible in our behavior. What may at first seem like a radical practice eventually becomes a day to day routine, with enhanced health for one's living landscape, local water ecosystems, one's pocketbook, and the planet as a whole. Try it and see!
