I hear you on Sphinx-- definitely looks like a great tool, though I haven't used it before. Do you know if Rails has something similar? Also, would you use sphinx to generate end-user docs (like the kind you find publicly available on Heroku, Twilio, SimpleGeo, PayPal, Hoptoad, etc.) or just internal docs? What level of control do you have over visibility of docs (i.e. can certain docs be private and others public?)?
