Demand for a BSD Associate Certification Guide

I have an idea for a new book. For the last year I have been part of
the BSD Certification Group (BSDCG). I started out as a Group member, but moved to the Advisory Board when TaoSecurity business occupied too much of my time.

Last month the BSDCG published its BSD Associate Exam Objectives (.pdf) The document outlines all the skills a candidate for the BSD Associate cert is expected to have. However, no specifics are given. For example:

3.2.12 Change the encryption algorithm used to encrypt the password database.

Concept:

Given a screenshot of a password database, the BSDA candidate should be
able to recognize the encryption algorithm in use and how to select
another algorithm. The candidate should also have a basic understanding
of when to use DES, MD5 and Blowfish.

Practical:
login.conf(5); auth.conf(5); passwd.conf(5); adduser.conf(5) and adduser(8)

I am considering writing a BSD Associate Certification Guide. The guide will cover all of the 7 domains on the cert:

1. Installing and Upgrading the OS and Software
2. Securing the OS
3. Files, Filesystems, and Disks
4. Users and Accounts Management
5. Basic System Administration
6. Network Administration
7. Basic Unix Skills

Half of the work is already done. I know everything that needs to be covered. What I need to do now is provide answers to the questions.

What do you think? Would you like a book that addresses all of the seven domains for all of the BSD OS' covered by the cert (FreeBSD, NetBSD, OpenBSD, DragonFly BSD)?
