Host-based security is a whole dead horse discussion, but I still believe Def-in-Dpht means "use everything you can get your hands on; reveal the least as possible." Correct me if I'm wrong: which OSes have desirable CSPRNG properties like Fortuna (entropy pools esp.). I've looked at OSX, Win8, Free/Net&Open BSD and still haven't found anything satisfying other than class of algo. (Ignore whether closed/open source and IP issues.) I would like to see all mainstream OSes do these well enough.
