I've used the "Humanure" method of dealing with fecal matter and I think it's the way to go.
I didn't do it quite like the book, which is linked below, suggests (I began that way, but altered it) and it worked flawlessly for years and is still the way human waste is handled at the off-grid straw/tire/etc. house I helped build. My former partner still lives there with her new husband and the setup we built is still going strong after 11 years (I visit often and always look forward to pooping there). Done right, it's totally safe and the resulting compost can be used on food crops.
Our setup was on a three-year rotation; the 1st year we filled the compost enclosure with all veggie scraps, weeds, and normally composted materials along with all feces, toilet paper, and urine (covering with straw/leaves/ some carbon source), adding wood ashes and/or water when necessary (not often).
At the end of the first year, our compost pile was just under 2 cubic yards (1.5 cubic meters) and we used pitchforks to chuck it all into a secondary enclosure right next to it and let it sit there for another year (I guess we flushed our toilet once a year, then).
After a year of sitting it had shrunk down to less than half its original volume and was safe to use on the veggie garden (the E. coli and other nasties were mostly pasteurized as the pile grew since our heap was usually -except in late Winter- around 130℉/54℃ and often went up to 160℉/71℃ but even if it never got hot, letting it sit a year ensures the pathogens would not survive). So in the 3rd year we pitched the 1st year's compost into the garden, the 2nd year's compost into the secondary bin, and the primary compost bin was ready to go, so to speak. We did this in Spring as soon as the pile wasn't frozen from winter anymore.
We only needed to add water because our pile was under a roof; we built it 'direct deposit' style meaning we climbed up a rope to a deck above the pile, opened the hatch door in the deck, and it was "bombs away!" I wasn't interested in using buckets and carrying it around and thought it was preferable to just go outside every time we needed to go. We built the roof after we got sick of being rained and snowed on while trying to 'relax.'
We were shy about growing root crops with it because we just couldn't shed all our inhibitions, though rationally we knew it would've been fine (but no health insurance made us extra-prudent). We even used to joke about how "If we are what we eat, then we haven't changed a bit!" Also, we learned that a test of someone's true level of experience in the outdoors is how willing and at what level of detail they're willing to talk about their own excrement. If you live outside it's something you confront the very first day you arrive, and every day thereafter. Even if you don't live outside it's an issue that 'conventional' methods (septic tank, sewer) deal with rather poorly, so I would see a humanure setup as an improvement to any existing infrastructure even if it comes with flush toilets (you know, those bowls of precious potable water many of us crap in).
The best part was that the whole setup cost about $200, and it's been working for 11 years without backing up once!
