Looks like you have been busy :)

A comment and an addition, I'd really drop the use of 'slave' entirely, it
also has a totally different meaning for bind, ie, a caching only
nameserver that passes all requests to another server, which is nothing
related to being a 'secondary' ... isc has mostly avoided using the term
lately because of this also...

Maybe a glossery....here's a start

RR      Resource record , ay of the A,MX,NS,TXT etc records
A       Authority Record
CNAME   Canonical Name (NB this is what the CNAME record points *TO*)
NS      NameServer Record
MX      MaileXchanger record
TXT     Text Record
TSIG    Transaction SIGnature (Encryption key) 

SOA     StartOfAuthority eg the name of the server of a zone
TTL     Time To Live - How long a RR is good for before it's obsolete
IN      Internet (record type, other uses for dns records are possible)
BIND    Berkeley Internet Name Domain (server) aka named
