Private reply.  I'm writing a new book on security; let me know if you want to
see the preface and ToC.  Right now, I'm working on the crypto chapter.  So --
in a book that stresses realistic security and paying attention to threat models,
what do I tell folks about petroleum herpetology?  Passwords are a different chapter;
so is process.  DRM is out of scope for this book.  But I don't really want to
advertise it this far in advance of completion at best, it will be released about a
year from now, and that's *if* I can finish it by May or June.
