  Errr, you are going to have to lock/order the update of the
named.conf (or its included) file at some point.  If you are already
doing that, you could very well lock/order the update of your tinydns
updates.  Depending on your needs, one is easier than the other.

  So what?  What DNS protocol allows you to kick/restart the secondary
bind server to tell it new zones are available?

  You make a lot of good points in your list but I'm already aware of
most of them.  Personally I think if you trim down your list to
about 8 points you'd have a LOT more credibility.  I'll leave it to
somebody else more familiar with dns to answer your issues (although
I am unaware of any djbdns expert hanging around in -chat).

  Once again, it depends on your needs.
