I was hoping to have more time to give detailed review of the 
recommendations, but I haven't yet. I do have an overall concern that 
the document is too BIND-centric, and by mixing the discussion of the 
concepts with the discussion of the implementation it makes the document 
much more difficult to understand, particularly for those who do not use 
BIND.

My first suggestion would be to split the document into concept and 
implementation pieces. In my mind the ideal way to handle the 
implementation (i.e., the BIND-specific instructions) would be in an 
appendix. You could refer to the appropriate section of the appendix at 
the end of the section that discusses the concept. This would also make 
it easier for people who want to contribute additional appendices with 
implementation instructions for other software to do so.

I'll try to follow up with more detailed discussion of the concepts 
discussed in the document if time allows.
